Matthew Dempsky 9f16620f46 [dev.regabi] cmd/compile: fix latent Sym.SetPkgDef issue
Sym.pkgDefPtr is supposed to return a pointer to the types.Object
variable currently holding the Sym's package-scope
definition. However, in the case of identifiers that were shadowed in
the current scope, it was incorrectly returning a pointer to a stack
copy of the dclstack variable, rather than a pointer into the dclstack
itself.

This doesn't affect PkgDef, because it only reads from the variable,
so it got the same result anyway. It also happens to not affect our
usage of SetPkgDef today, because we currently only call SetPkgDef for
the builtin/runtime.go symbols, and those are never shadowed.

However, it does affect my upcoming CL to lazily create the ir.Names
for imported objects, as that depends on the ability to use SetPkgDef
to set shadowed identifiers.

Passes buildall w/ toolstash -cmp.
