Gabor Buella 890e363e11 [X86] Lowering FMA intrinsics to native IR (LLVM part) 
Support for Clang lowering of fused intrinsics. This patch:

1. Removes bindings to clang fma intrinsics.
2. Introduces new LLVM unmasked intrinsics with rounding mode:
     int_x86_avx512_vfmadd_pd_512
     int_x86_avx512_vfmadd_ps_512
     int_x86_avx512_vfmaddsub_pd_512
     int_x86_avx512_vfmaddsub_ps_512
     supported with a new intrinsic type (INTR_TYPE_3OP_RM).
3. Introduces new x86 fmaddsub/fmsubadd folding.
4. Introduces new tests for code emitted by sequentions introduced in Clang part.
