go/src/cmd/compile/internal/ssa/rewritegeneric.go
Keith Randall a1b802bde7 cmd/compile: move some generic rules to strongly typed 
Move a lot of the constant folding rules to use strongly
typed AuxInt fields.

We need more than a cast to convert AuxInt to, e.g., float32.
Make conversion functions for converting back and forth.
