Added FMA3 Intel instructions.
I disabled FMA3 autodetection, since the result may differ from expected for some benchmarks. I added tests for GodeGen and intrinsics. I did not change llvm.fma.f32/64 - it may be done later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157737 91177308-0d34-0410-b5e6-96231b3b80d8
