[PATCH] D82258: [RegisterCoalescer] Fix IMPLICIT_DEF init removal for a register on joining

[Quentin Colombet via Phabricator via llvm-commits]

qcolombet added a comment.

Honestly, I have no idea one way or another. I'm leaning toward @arsenm's theory that the implicit def may be needed in case the full register is never fully covered.
But I would need to dig deeper into this.
