cmd/compile/internal/ssa: split helpers

We're going to move the rewrites to their own packages in the
next CL. To do that we're going to move the helpers out
of the ssacompile package. Helpers used by multiple
packages have been exported and will be relocated to the ssa package,
while helpers only used by one of the rewrites will be
left unexported and moved to a dedicated file that will
be moved in the next CL along with the actual rewrites.

For #80409
