  Changed paths:

    M llvm/test/Transforms/SROA/std-clamp.ll

  Log Message:
  -----------
  [Analysis] isDereferenceableAndAlignedPointer(): recurse into select's hands

By doing this within the method itself,
we support traversing multiple levels of selects (TODO: PHI's),
fixing the SROA `std::clamp()` testcase.
