Revert "liblink, cmd/ld, runtime: remove stackguard1"
This reverts commit ab0535ae3fb45ba734d47542cc4845f27f708d1b.
I think it will remain useful to distinguish code that must
run on a system stack from code that can run on either stack,
even if that distinction is no
longer based on the implementation language.
That is, I expect to add a //go:systemstack comment that,
in terms of the old implementation, tells the compiler,
to pretend this function was written in C.
