- Move all MOVSS and MOVSD patterns close to their definitions
- Duplicate some store patterns to their AVX forms! - Catched a bug while restricting the patterns subtarget, fix it and update a testcase to check it properly git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138851 91177308-0d34-0410-b5e6-96231b3b80d8
