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.
