[PATCH] D46329: [SelectionDAG] Selection of DBG_VALUE using a PHI node result (pt 2)

[Bjorn Pettersson via Phabricator via llvm-commits]

bjope updated this revision to Diff 144786.
bjope added a comment.

Some updates suggested by vsk:

- Use zip_first.
- Add a RegsForValue::occupiesMultipleRegisters() helper.
- Cleanup in the test case (removing tbaa and lifetime stuff).

I'll create another patch to do a similar refactoring in EmitFuncArgumentDbgValue (or see if we can share code in some way).
