This is a port of CL 340911 to go/types. The new check differs slightly,
due to go/ast storing type parameters on the function type, rather than
declaration. The error was positioned on the function name for
consistency with types2 (and because that's a better position).

Currently, for hidden closures, we always push them to compile queue
during typechecking. If the hidden closure is discarded from the outer
function body during deadcode, any desugaring phase after deadcode won't
be applied to the closure. Thus, some un-expected OPs are passed to
downstream passes, which they can't handle, the compiler goes boom!
To fix this, we keep track of discarded hidden closures during deadcode
pass, and won't compile them then.

In asmcgocall() we need to switch to the g0 stack if we're not already on

check gsignal first, then g0, since if we are going to switch to g0 we will
need g0 handy (thus avoiding a second load).
Rewrite/reorder 386 and amd64 to check gsignal first - this shaves a few
assembly instructions off and makes the order consistent with arm, arm64,
mips64 and ppc64. Add missing gsignal checks to mips, riscv64 and s390x.

Exposing a synthetic type name for instantiated types is problematic:
there is no way to ensure that type instances are first created in the
same type checking pass, and therefore no guarantee that their
instantiation positions are the same. Even type checking a given package
with different file ordering could result in different positions being
associated with type instances. This is therefore an implementation
detail that we should not expose.
Keep the synthetic type name for accurate error reporting, but hide it

Instantiate and InstantiateLazy have the same signature; on first
principles, if Instantiate should work for importers it should be
possible to consolidate these APIs.
This CL does this. In order to make it work, a typMap needs to be
threaded through type expansion to prevent infinite recursion in the
case that the Checker is nil.
Notably, Named types now must be expanded before returning from
Underlying(). This makes Underlying generally unsafe to call while type
checking a package, so a helper function safeUnderlying is added to
provide the previous behavior. This is probably overly conservative at
most call sites, but cleanup is deferred to a later CL.
