Reduce the number of copies emitted as machine instructions by generating results in vregs that will need them. In the case of something like this: CopyToReg((add X, Y), reg1024), we no longer emit code like this: reg1025 = add X, Y reg1024 = reg 1025 Instead, we emit: reg1024 = add X, Y Whoa! :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24111 91177308-0d34-0410-b5e6-96231b3b80d8
