llvm/test/CodeGen/X86/fma-intrinsics-phi-213-to-231.ll
Andrew Kaylor 80a2456665 Created new X86 FMA3 opcodes (FMA*_Int) that are used now for lowering of scalar FMA intrinsics. 
Patch by Slava Klochkov 

The key difference between FMA* and FMA*_Int opcodes is that FMA*_Int opcodes are handled more conservatively. It is illegal to commute the 1st operand of FMA*_Int instructions as the upper bits of scalar FMA intrinsic result must be taken from the 1st operand, but such commute transformation would change those upper bits and invalidate the intrinsic's result.

Reviewers: Quentin Colombet, Elena Demikhovsky
