as an (index,bool) pair. The bool flag records whether the kill is a PHI kill or not. This code will be used to enable splitting of live intervals containing PHI-kills. A slight change to live interval weights introduced an extra spill into lsr-code-insertion (outside the critical sections). The test condition has been updated to reflect this. llvm-svn: 75097
