X86: Make shuffle -> shift conversion more aggressive about undefs. Shuffles that only move an element into position 0 of the vector are common in the output of the loop vectorizer and often generate suboptimal code when SSSE3 is not available. Lower them to vector shifts if possible. We still prefer palignr over psrldq because it has higher throughput on sandybridge. llvm-svn: 182102

Massive rewrite of MMX: The x86_mmx type is used for MMX intrinsics, parameters and return values where these use MMX registers, and is also supported in load, store, and bitcast. Only the above operations generate MMX instructions, and optimizations do not operate on or produce MMX intrinsics. MMX-sized vectors <2 x i32> etc. are lowered to XMM or split into smaller pieces. Optimizations may occur on these forms and the result casted back to x86_mmx, provided the result feeds into a previous existing x86_mmx operation. The point of all this is prevent optimizations from introducing MMX operations, which is unsafe due to the EMMS problem. llvm-svn: 115243
