[llvm] [InstCombine][nfc] Remove dead invoke inst check in foldOpIntoPhi (PR #161871)

[Cullen Rhodes via llvm-commits]

https://github.com/c-rhodes created https://github.com/llvm/llvm-project/pull/161871

There's a check above the pred block is terminated with an unconditional branch, so this code is unreachable.
