  -----------
  [AMDGPU] performCvtF32UByteNCombine - revisit node after src operand simplification.

If SimplifyDemandedBits succeeds in simplifying the byte src, add the CVT_F32_UBYTE node back to the worklist as we might be able to simplify further.

Yet another step towards removing SelectionDAG::GetDemandedBits.

  Changed paths:
    M clang/lib/Sema/SemaExprCXX.cpp

  Log Message:
  -----------
  Fix some getAs/castAs null dereference static analyzer warnings.

Use castAs if we know the cast should succeed (or we're dereferencing without check), the castAs will assert as well so we can remove local non-null asserts.
