When a live virtual register is being clobbered by an implicit def, it is spilled and the spill is its kill. However, if the local allocator has determined the register has not been modified (possible when its value was reloaded), it would not issue a restore. In that case, mark the last use of the virtual register as kill. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46111 91177308-0d34-0410-b5e6-96231b3b80d8
