  -----------
  [ConstantFolding] Avoid use of isNonIntegralPointerType()

Avoiding any new inttoptr is unnecessarily restrictive for "plain"
non-integral pointers, but it is important for unstable pointers and
pointers with external state. Fixes another test codegen regression
from https://github.com/llvm/llvm-project/pull/105735.
