CPU: Implement VFNMS.F32/64 (#1758)
* Add necessary methods / op-code

* Enable Support for FMA Instruction Set

* Add Intrinsics / Assembly Opcodes for VFMSUB231XX.

* Add X86 Instructions for VFMSUB231XX

* Implement VFNMS

* Implement VFNMS Tests

* Add special cases for FMA instructions.

* Update PPTC Version

* Remove unused Op

* Move Check into Assert / Cleanup

* Rename and cleanup

* Whitespace

* Whitespace / Rename

* Re-sort

* Address final requests

* Implement VFMA.F64

* Simplify switch

* Simplify FMA Instructions into their own IntrinsicType.

* Remove whitespace

* Fix indentation

* Change tests for Vfnms -- disable inf / nan

* Move args up, not description ;)

* Undo vfma

* Completely remove vfms code.,

* Fix order of instruction in assembler
