Nikita Popov 9a844a36eb [InstCombine] Use InstSimplify in FoldOpIntoSelect (#116073) ...

Instead of only trying to constant fold the select arms, try to simplify
them. This subsumes https://github.com/llvm/llvm-project/pull/115969
which implements this for extractvalue only.

This is still fairly limited in that we will usually only call
FoldOpIntoSelect in the first place if we have a constant operand. This
can be relaxed in the future if worthwhile.
