    M llvm/test/Transforms/InstCombine/annotations.ll

  Log Message:
  -----------
  [InstCombine] Preserve !annotation for newly created instructions.

When replacing an instruction with !annotation with a newly created
replacement, add the !annotation metadata to the replacement.

This mostly covers cases where the new instructions are created using
the ::Create helpers. Instructions created by IRBuilder will be handled
by D91444.
