[dev.regabi] cmd/compile: cleanup preparing for concrete types, 2

Browse source 
Avoid using the same variable for two different concrete
Node types in other files (beyond walk). This will smooth the
introduction of specific constructors, replacing ir.Nod and friends.

Passes buildall w/ toolstash -cmp.

Replay of CL 275885, lost to the bad-merge history rewrite.
