[CostModel][X86] Improve masked load/store AVX1/AVX2 costs
A mixture of internal tests and review of the scheduler models indicates we're overestimating the cost of a masked load, which we're estimating at 4x regular memory ops - more realistic values indicates that its closer to 2x. Masked stores costs are a lot more diverse but 8x is roughly in the middle of the range. e.g. SandyBridge defm : X86WriteRes<WriteFMaskedLoad, [SBPort23,SBPort05], 8, [1,2], 3>; defm : X86WriteRes<WriteFMaskedLoadY, [SBPort23,SBPort05], 9, [1,2], 3>; defm : X86WriteRes<WriteFMaskedStore, [SBPort4,SBPort01,SBPort23], 5, [1,1,1], 3>; defm : X86WriteRes<WriteFMaskedStoreY, [SBPort4,SBPort01,SBPort23], 5, [1,1,1], 3>; e.g. Btver2 defm : X86WriteRes<WriteFMaskedLoad, [JLAGU, JFPU01, JFPX], 6, [1, 2, 2], 1>; defm : X86WriteRes<WriteFMaskedLoadY, [JLAGU, JFPU01, JFPX], 6, [2, 4, 4], 2>; defm : X86WriteRes<WriteFMaskedStore, [JSAGU, JFPU01, JFPX], 6, [1, 1, 4], 1>; defm : X86WriteRes<WriteFMaskedStoreY, [JSAGU, JFPU01, JFPX], 6, [2, 2, 4], 2>; Differential Revision: https://reviews.llvm.org/D61257 llvm-svn: 362338
