[ARM64] Set default CPU to generic instead of cyclone. llvm-svn: 206313

ARM64: initial backend import This adds a second implementation of the AArch64 architecture to LLVM, accessible in parallel via the "arm64" triple. The plan over the coming weeks & months is to merge the two into a single backend, during which time thorough code review should naturally occur. Everything will be easier with the target in-tree though, hence this commit. llvm-svn: 205090

[DAGCombiner] Combine shuffles of BUILD_VECTOR and SCALAR_TO_VECTOR This patch attempts to fold the shuffling of 'scalar source' inputs - BUILD_VECTOR and SCALAR_TO_VECTOR nodes - if the shuffle node is the only user. This folds away a lot of unnecessary shuffle nodes, and allows quite a bit of constant folding that was being missed. Differential Revision: http://reviews.llvm.org/D8516 llvm-svn: 234004

[SDAG] Teach the SelectionDAG to canonicalize vector shuffles of splats directly into blends of the splats. These patterns show up even very late in the vector shuffle lowering where we don't have any chance for DAG combining to kick in, and blending is a tremendously simpler operation to model. By coercing the shuffle into a blend we can much more easily match and lower shuffles of splats. Immediately with this change there are significantly more blends being matched in the x86 vector shuffle lowering. llvm-svn: 229308
