CPU: Implement VFMA (Vector) (#1762)
* 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 ;)

* Implementation Complete.

All Tests Pass (Slow / Fast Path)

* Move location of function in assembler + test updates.

* Shift params upwards

* Remove unused function

* Update PTC version.

* Add comments / re-oreder opcode table.

* Remove whitespace

* Fix nit

* Fix nit.

* Fix whitespace

* Wrong opcode was used by a bad merge.

* Addressed rip's comments.
