[PATCH] D95564: [GlobalISel] Add G_ASSERT_ZEXT

[Amara Emerson via Phabricator via llvm-commits]

We should clarify what kind of copies this is allowed to do. As a hint, I think it shouldn't be legal to use this copy to change regbanks, or regclasses, or to use/define physical registers. As a hint, it should be guaranteed to be safe to look through to the vreg source.
