    M llvm/test/Transforms/InstCombine/select-safe-transforms.ll

  Log Message:
  -----------
  [InstCombine] match logical and/or more generally in fold to select

This allows the regular bitwise logic opcodes in addition to the
poison-safe select variants:

Handling commuted variants safely is likely trickier, so that's
left to another patch.
