[PATCH] D157273: [GlobalISel] Add dead flags to implicit defs in ISel

[Pierre van Houtryve via Phabricator via llvm-commits]

Pierre-vh added a comment.

A couple of things to note:

- This is a bit naive, it only works on the `Record*` and doesn't test for subregs or RC, should it?
- One of the tradeoffs of doing this at the TableGen level is that we don't know about reserved registers. Do they matter in this case? How could we handle them?
