Implement XMM subregs. Extracting the low element of a vector is now done with EXTRACT_SUBREG, and the zero-extension performed by load movss is now modeled with SUBREG_TO_REG, and so on. Register-to-register movss and movsd are no longer considered copies; they are two-address instructions which insert a scalar into a vector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97354 91177308-0d34-0410-b5e6-96231b3b80d8
