FMA3 tests on bdver2 target for changes made in rev 162012. Also made corresponding changes to existing tests for darwin triple to ensure that same pattern is tested for bdver2 target. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162655 91177308-0d34-0410-b5e6-96231b3b80d8

Add an intrinsic and codegen support for fused multiply-accumulate. The intent is to use this for architectures that have a native FMA instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134742 91177308-0d34-0410-b5e6-96231b3b80d8
