Craig Topper fd53b80219 Rename fma4 intrinsics to just fma since they are now used for both FMA4 and FMA3. Autoupgrade support coming in a separate commit.

Elena Demikhovsky 602f3a26d6 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.
