[PATCH] D105925: [TableGen] Warn when patterns are ignored due to impossible types

[Thomas Lively via Phabricator via llvm-commits]

tlively added a comment.

I have to admit that I don't understand what situations the comment is describing where we would want to ignore an impossibly-typed pattern. This new warning is not emitted by any of the upstream backends, so I'm wondering if we should update the comment and make this a hard error instead.
