Add a new target independent COPY instruction and code to lower it. The COPY instruction is intended to replace the target specific copy instructions for virtual registers as well as the EXTRACT_SUBREG and INSERT_SUBREG instructions in MachineFunctions. It won't we used in a selection DAG. COPY is lowered to native register copies by LowerSubregs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107529 91177308-0d34-0410-b5e6-96231b3b80d8
