cmd/compile/internal/gc: unexport more helper functions

Browse source 
After the removal of the old backend many types are no longer referenced
outside internal/gc. Make these functions private so that tools like
honnef.co/go/unused can spot when they become dead code. In doing so
this CL identified several previously public helpers which are no longer
used, so removes them.

This should be the last of the public functions.
