cmd/compile: remove gins

Browse source 
The only remaining consumers of gins were
ginsnop and arch-independent opcodes like GVARDEF.
Rewrite ginsnop to create and populate progs directly.
Move arch-independent opcodes to package gc
and simplify.
Delete some now unused code.
There is more.
Step one towards eliminating gc.Node.Reg.
