Improved tracking of value number kills. VN kills are now represented
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75097 91177308-0d34-0410-b5e6-96231b3b80d8
