cmd/compile/internal/types2: slightly relax notion of structural type
If we have all channel types in a constraint, there is no structural type
if they don't all have the same channel direction (and identical element
types, of course). By allowing different channel types for the purposes of
the structural type, as long as there is not a send-only _and_ a receive-
only channel in the type set, we make it possible to find a useful, if
restricted by channel direction, structural type where before there was
none.
So if we have unrestricted and send-only channels, the structural type is
the send-only channel, and vice versa.
For all operations on channels that rely on a structural type, it's always
ok to have an unrestricted channel, so this is not affecting their behavior.
But it makes those operations more flexible in the presence of type parameters
containing mixed channel types.
For constraint type inference, where we currently may not infer a channel
at all, this change allows us to infer a more restricted channel (send- or
receive-only). If the inferred channel type is a valid type argument we win;
if not we haven't lost anything.
Use structuralType for send and receive operations and adjust related
error messages (the error message that change are the ones involving
type parameters, so historic error messages are preserved).

cmd/compile: don't do Resolve on OKEY identifiers during import
For generic functions, we can export untransformed OKEY nodes, and the
key identifier is written as an ONONAME. But in this case, we do not
want to call Resolve() on the identifier, since we may resolve to a
global type (as happens in this issue) or other global symbol with the
same name, if it exists. We just want to keep the key identifier as an
Ident node.
To solve this, I added an extra bool when exporting an ONONAME entry,
which indicates if this entry is for a key or for a global (external)
symbol. When the bool is true (this is for a key), we avoid calling
Resolve().

cmd/go: add workspace pruning mode
[ this is a roll-forward of golang.org/cl/357169 with minor changes
to fix the cmd/go/internal/modload tests: because they don't run the
go command, some initialization isn't run on the test and modroots is
empty in cases it can't be when the full command setup is done. So
directly check for workFilePath != "" instead of calling inWorkspaceMode
which checks that Init is called first, and check that modRoots is non
empty when calling mustGetSingleMainModule.]
This change corrects a bug in the handling of module loading of
workspaces. Namely, there is an assumption by the module pruning code
that if a root module is selected then the packages of that module can
be resolved without loading the whole module graph. This is not true
in workspace mode because two workspace modules can require different
versions of a dependency. Worse, one workspace module can directly
require a depencency that is transitively required by another
workspace module, changing the version of that module loaded in the
fully expanded graph.
To correct this, a new 'workspace' pruning mode is added where the
roots are the workspace modules themselves, satisfying the assumption
made by the module pruning logic.
The rest of this change accounts for the new pruning mode where it's
used and correctly sets the requirements in this pruning mode.

cmd/go: add workspace pruning mode
This change corrects a bug in the handling of module loading of
workspaces. Namely, there is an assumption by the module pruning code
that if a root module is selected then the packages of that module can
be resolved without loading the whole module graph. This is not true
in workspace mode because two workspace modules can require different
versions of a dependency. Worse, one workspace module can directly
require a depencency that is transitively required by another
workspace module, changing the version of that module loaded in the
fully expanded graph.
To correct this, a new 'workspace' pruning mode is added where the
roots are the workspace modules themselves, satisfying the assumption
made by the module pruning logic.
The rest of this change accounts for the new pruning mode where it's
used and correctly sets the requirements in this pruning mode.

runtime: disable GC in TestPanicSystemstack's subprocess
TestPanicSystemstack spins up a subprocess that has 2 goroutines
deadlock on a runtime lock while on the system stack, with GOMAXPROCS=2.
Each goroutine is going to be running on a P, and then is going to wedge
itself up on that P.
If a GC is active and a worker starts executing (using a P), then it
could try to preempt a goroutine that is already blocked. It won't be
able to, so it'll just sit there forever trying to suspend it. At this
point there are no more Ps to execute the remaining goroutine that needs
to print something so the parent process can continue the test.
This change fixes this issue by disabling GCs in the child process. An
alternative fix could be to increase GOMAXPROCS in the child, but maybe
letting the GC be on (which assumes it'll always be able to *eventually*
suspend a G) is just asking for trouble.

runtime: disable GC during debug call tests
Currently the debug call protocol implementation we use for testing is
riddled with write barriers, and called from a signal handler. This is
not safe, as write barriers need a P to execute.
Ideally this implementation would be rewritten to avoid the write
barriers, but it's not straightforward, and needs some thought. As a
temporary measure, disable GC during the debug call tests to avoid a
write barrier.
Note that this does not indicate a problem with real use of the debug
call protocol. Only our test implementation has this issue, because it
needs to get executed in a signal handler, normally a separate process
is interfacing with the protocol via process signals and ptrace (and the
like).

archive/zip: don't read data descriptor early
Go 1.17 introduced an unnecessary change to when a zip's data descriptor
is read for file entries, how it is parsed and how the crc32 field is
used.
Before Go 1.17, the data descriptor was read immediately after a file
entry's content. This continuous read is a pattern existing applications
have come to rely upon (for example, where reads at specific offsets
might be translated to HTTP range requests).
In Go 1.17, all data descriptors are immediately read upon opening the
file. This results in scattered and non-continuous reads of the archive,
and depending on the underlying reader, might have severe performance
implications. In addition, an additional object is now initialized for
each entry, but is mostly redundant.
Previously, the crc32 field in the data descriptor would return an error
if it did not match the central directory's entry. This check has
seemingly been unintentionally removed. If the central directory crc32
is invalid and a data descriptor is present, no error is returned.
This change reverts to the previous handling of data descriptors, before
CL 312310.

We don't need to distinguish anymore as this is the new default.
This removes the need to prefix test package names with "generic_".

crypto/x509: verification with system and custom roots
Make system cert pools special, such that when one has extra roots
added to it we run verifications twice, once using the platform
verifier, if available, and once using the Go verifier, merging the
results.
This change re-enables SystemCertPool on Windows, but explicitly does
not return anything from CertPool.Subjects (which matches the behavior
of macOS). CertPool.Subjects is also marked deprecated.

cmd/compile: avoid adding LECall to the entry block when has opendefers
The openDeferRecord always insert vardef/varlive pairs into the entry block, it may destroy the mem chain when LECall's args are writing into the same block. So create a new block before that happens.

crypto/x509: use platform verifier on darwin
When VerifyOptions.Roots is nil, default to using the platform X.509
certificate verification APIs on darwin, rather than using the Go
verifier. Since our oldest supported version of macOS is 10.12, we are
able to use the modern verification APIs, and don't need to resort to
the complex chain building trickery employed by chromium et al.
Unfortunately there is not a clean way to programmatically add test
roots to the system trust store that the builders would tolerate. The
most obvious solution, using 'security add-trusted-cert' requires human
interaction for authorization. We could also manually add anchors to
the constructed SecTrustRef, but that would require adding a whole
bunch of plumbing for test functionality, and would mean we weren't
really testing the actual non-test path. The path I've chosen here is
to just utilize existing valid, and purposefully invalid, trusted
chains, from google.com and the badssl.com test suite. This requires
external network access, but most accurately reflects real world
contexts.
This change removes the x509.SystemCertPool() functionality, which will
be ammended in a follow-up change which supports the suggested hybrid
pool approach described in #46287.

This change allows the check to pass unmodified under GopherJS, which

NodeJS). There are no other functions named `interestingGoroutines` in
the standard library, so it's very unlikely to create false negatives,
and will allow reduce the number of overlays GopherJS needs to maintain.
