  [InstCombine] Call InstSimplify for cast instructions (#162849)

InstCombine currently fails to call into InstSimplify for cast
instructions. I noticed this because the transform from
https://github.com/llvm/llvm-project/pull/98649 can be triggered via
`-passes=instsimplify` but not `-passes=instcombine`, which is not
supposed to happen.
