  Revert "[clang] Add nuw attribute to GEPs" (#106343)

Reverts llvm/llvm-project#105496

This patch breaks:
https://lab.llvm.org/buildbot/#/builders/25/builds/1952
https://lab.llvm.org/buildbot/#/builders/52/builds/1775

Somehow output is different with sanitizers.
Maybe non-determinism in the code?
