  [InstCombine] Avoid invalid bitcast across address spaces in foldIntegerTypedPHI (#181064)

Only use a PtrToInt's source pointer as an available pointer value when
its pointer type exactly matches the inttoptr target type. This prevents
creating an invalid bitcast between differing address spaces during
foldIntegerTypedPHI.
