*	Mark rematerialized super/sub registers as dead.	Tim Northover	2013-06-14
	When we're rematerializing into a not-quite-right register we already add the real definition as an imp-def, but we should also be marking the "official" register as dead, since nothing else is going to use it as a result of this remat. Not doing this can affect pressure tracking. rdar://problem/14158833 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184002 91177308-0d34-0410-b5e6-96231b3b80d8
