The gccgo runtime is based on the gc runtime. It is not identical.
Changes in the gc runtime are periodically merged into the gccgo
runtime, and I resolve the merge conflicts by hand.
It will never make sense to use the exact same data structures for the
gccgo stack frame, because the stack frame is fundamentally different.
gccgo will require a different approach, hopefully similar in general
but certainly different in specific details.
