On the VP side: Fast-math flag transfer from VP intrinsics to VP SDNodes. Tested through the VE parts of this patch.   
For VE: Custom fusion code for VVP_FMA. Yes, there could/should be a generic DAGCombiner path for this, however, this is just the first in a series of VE-specific combiner patterns.
