[dev.regabi] cmd/compile: add ir.Closure, ir.ClosureRead

Browse source 
Closures are another reference to Funcs,
and it cleans up the code quite a bit to be clear about types.

OCLOSUREVAR is renamed to OCLOSUREREAD to make
clearer that it is unrelated to the list Func.ClosureVars.

Passes buildall w/ toolstash -cmp.
