Simon Pilgrim b5024feb68 [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>;

The LLVM Compiler Infrastructure
================================

This directory and its subdirectories contain source code for LLVM,
a toolkit for the construction of highly optimized compilers,
optimizers, and runtime environments.

LLVM is open source software. You may freely distribute it under the terms of
the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.

If you are writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
