AMDGPU: Fold out sign bit ops on frexp_exp
The sign bit has no impact on the exponent, so strip these away. Saves
on the source modifier encoding cost. I left the GlobalISel handling
until there's a resolution to issue #62628.
We should do this in instcombine too, but legalization should be
introducing more frexps than it currently is where this would occur.
