- Mark last use of a split interval as kill instead of letting spiller track it. This allows an important optimization to be re-enabled. - If all uses / defs of a split interval can be folded, give the interval a low spill weight so it would not be picked in case spilling is needed (avoid pushing other intervals in the same BB to be spilled). llvm-svn: 44601
