Justin Bogner 866d9f02be [VirtRegRewriter] Avoid clobbering registers when expanding copy bundles 
If a copy bundle happens to involve overlapping registers, we can end
up with emitting the copies in an order that ends up clobbering some
of the subregisters. Since instructions in the copy bundle
semantically happen at the same time, this is incorrect and we need to
make sure we order the copies such that this doesn't happen.
