[PATCH] Add intrinsic definitions for unary op AVX instructions [x86]

[Elena Demikhovsky]

You actually can use one class to define all instruction (FR32, FR64) and intrinsics (VR128) using COPY_TO_REGCLASS. in order to convert VR128 to FR32 or FR64.
See http://reviews.llvm.org/rL229837.

You also can define  V#NAME#SDm_Int, if you don't like the COPY_TO_REGCLASS patterns.
There are too many intrinsics. I don't think that we should put them all in the peephole optimization pass.
