Keith Randall a2adbc876e [release-branch.go1.15] cmd/compile: sign extend consant folding properly
MOVLconst must have a properly sign-extended auxint constant.
The bit operations in these rules don't enforce that invariant.

The easiest fix is just to turn on properly typed auxint fields
(which is what fixed this issue at tip).

Fixes #42753
