    A llvm/test/Transforms/SLPVectorizer/X86/reduction-with-removed-extracts.ll

  Log Message:
  -----------
  [SLP]Check if the operand for removal is the reduction operand, awaiting for the reduction

If the operand of the instruction-to-be-removed is a reduction value,
which is not reduced yet, and, thus, it has no users, it may be removed
during operands analysis.

Fixes #128736
