cmd/compile: make rulegen magic variable prediction more precise 

The sheer length of the generated rules files makes my
editor and git client unhappy.
This change is a small step towards shortening them.

We recognize a few magic variables during rulegen: b, config, fe, typ.
Of these, only b appears prone to false positives.
By tightening the heuristic and fixing one case in MIPS.rules,
we can make the heuristic enough that it has no failures.
That allows us to remove the hedge assignments to _,
removing 3000 pointless lines of code.
