[dev.regabi] cmd/compile: exporting, importing, and inlining functions with OCLOSURE
I have exporting, importing, and inlining of functions with closures
working in all cases (issue #28727). all.bash runs successfully without
errors.
Approach:
- Write out the Func type, Dcls, ClosureVars, and Body when exporting
an OCLOSURE.
- When importing an OCLOSURE, read in the type, dcls, closure vars,
and body, and then do roughly equivalent code to (*noder).funcLit
- During inlining of a closure within inlined function, create new
nodes for all params and local variables (including closure
variables), so they can have a new Curfn and some other field
values. Must substitute not only on the Nbody of the closure, but
also the Type, Cvars, and Dcl fields.
Fixes #28727
