  Changed paths:
    M llvm/lib/Transforms/InstCombine/InstCombineSelect.cpp
    M llvm/test/Transforms/InstCombine/select-safe-transforms.ll

  Log Message:
  -----------
  [InstCombine] allow more commutative matches for logical-and to select fold

When the common value is part of either select condition,
this is safe to reduce. Otherwise, it is not poison-safe
(with the select form of the pattern):

This is another patch motivated by issue #58313.
