  Revert "[SeparateConstOffsetFromGEP] Decompose constant xor operand if possible (#135788)"

This reverts commit 13ccce28776d8ad27b0c6a92b5a452d62da05663.

The tests are on non-canonical IR, and adds an extra unrelated
pre-processing step to the pass. I'm assuming this is a workaround
for the known-bits recursion depth limit in instcombine.
