cmd/compile: eliminate PPARAMREF

Browse source 
As in the elimination of PHEAP|PPARAM in CL 23393,
this is something the front end can trivially take care of
and then not bother the back ends with.
It also eliminates some suspect (and only lightly exercised)
code paths in the back ends.

I don't have a smoking gun for this one but it seems
more clearly correct.
