    A llvm/test/CodeGen/X86/pr46532.ll

  Log Message:
  -----------
  [LegalizeTypes] Properly handle the case when UpdateNodeOperands in PromoteIntOp_MLOAD triggers CSE instead of updating the node in place.

The caller can't handle the node having multiple results like a
masked load does. So we need to detect the case and do our own
result replacement.

Fixes PR46532.
