    A llvm/test/Transforms/SLPVectorizer/X86/user-buildvector-with-minbiwidth.ll

  Log Message:
  -----------
  [SLP]Fix the analysis of the user buildvector nodes for minbitwidth

If the user node is a buildvector/gather node and it has no internal
instructions state, need to check properly for this state and check the
type of the node itself, not its operands.

Fixes #129242
