  GlobalISel: Add FoldBinOpIntoSelect combine

This will do the combine in cases that should fold, but don't
now. e.g. we're relying on the CSEMIRBuilder's incomplete constant
folding. For instance it doesn't handle FP operations or vectors (and
we don't have separate constant folding combines either to catch
them).
