* Fix Vnmls_S fast path (F64: losing input d value). Fix Vnmla_S & Vnmls_S slow paths (using fused inst.s). Add Vfma_S & Vfms_S Fma fast paths. Add Vfnma_S inst. with Fma/Sse fast paths and slow path. Add Vfnms_S Sse fast path. Add Tests for affected inst.s. Nits. * InternalVersion = 1775 * Nits. * Fix Vfma_V slow path not using StandardFPSCRValue(). * Nit: Fix Vfma_V order. * Add Vfms_V Sse fast path and slow path. * Add Vfma_V and Vfms_V Test.
