cmd/compile: change some unreachable code paths into Fatalf
Now that GOEXPERIMENT=nounified is removed, we can assume InlineCall
and HaveInlineBody will always be overridden with the unified
frontend's implementations. Similarly, we can assume expandDecl will
never be called.
This CL changes the code paths into Fatalfs, so subsequent CLs can
remove all the unreachable code.
Updates #57410.
