Matt Arsenault 841a0edd03 ConstantFolding: Constant fold some canonicalizes 
+/-0 is obviously foldable. Other non-special, non-subnormal
values are also probably OK. For denormal values, check
the calling function's denormal mode. For now, don't fold
denormals to the input for IEEE mode because as far as I know
the langref is still pretending LLVM's float isn't IEEE.

Also folds undef to 0, although NaN may make more sense. Skips
folding nans and infinities, although it should be OK to fold those
in a future change.
