Subject: Fix Vnmls_S fast path (F64: losing input d value). Fix Vnmla_S &
 Vnmls_S slow paths (using fused inst.s). Fix Vfma_V slow path not using
 StandardFPSCRValue(). (#1775)

* 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.
