[PATCH] D135411: Add generic KCFI operand bundle lowering

[Sami Tolvanen via Phabricator via cfe-commits]

Dropped the CodeGen dependency. Note that Clang already only adds KCFIPass for targets that don't support back-end lowering, so the check in the pass itself was a bit redundant. The existing CodeGen/kcfi.c test also ensures we continue to emit kcfi operand bundles.
