[InstCombine] Fix inversion of constants

`canFreelyInvertAllUsersOf()`, in general, does not make sense
for constants, and constant expressions are likely even more problematic.
For those, we just want to create a simple constant expression and be done.

Fixes https://github.com/llvm/llvm-project/issues/59613
