Two changes, both very significant: * vreg <-> vreg joining now works, enable it unconditionally when joining is enabled (which is the default). * Fix a serious pessimization of spill code where we were saying that a spilled DEF operand was live into the subsequent instruction. This allows for substantially better code when spilling starts to happen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14993 91177308-0d34-0410-b5e6-96231b3b80d8
