Craig Topper 7034d401f8 [X86] Use mattr instead of mcpu in some of the cost model tests.
Based on the names of the check lines, features seems more appropriate that cpu.

Spotted while prototyping my patch to make 512-bit vectors illegal on SKX sometimes.

Simon Pilgrim 2d1c6d6e8d [X86][AVX1] Improve 256-bit vector costs for integer unary intrinsics.
Account for subvector extraction/insertion, helps prevent the vectorizers from selecting 256-bit vectors that will have to be split anyhow on AVX1 targets.

Simon Pilgrim 14000b3cea [CostModel][X86][XOP] Added XOP costmodel for BITREVERSE
Now that we have a nice fast VPPERM solution. Added framework for future intrinsic costs as well.
