[PATCH] D141192: [Clang] Add warnings on bad shifts inside enums.

[Shafik Yaghmour via Phabricator via cfe-commits]

shafik added a comment.

So it looks like in `handleIntIntBinOp` we do hit this code:

  unsigned SA = (unsigned) RHS.getLimitedValue(LHS.getBitWidth()-1);
   if (SA != RHS) {
     Info.CCEDiag(E, diag::note_constexpr_large_shift)
       << RHS << E->getType() << LHS.getBitWidth();

So maybe we should figure out why we decide not to emit this diagnostic and fix it there.
