Revert "[InstCombine] enhance fold for subtract-from-constant -> xor"

This reverts commit 79bb915fb60b2cd220d89e3bb54f67abb8cdb7bd.
This caused regressions because SCEV works better with sub.

[PhaseOrdering][SystemZ] add test for combining/unrolling; NFC

As discussed in D128123, this test is based on an example
that ends up with codegen regressions if sub is converted
to xor.
