Ryan Houdek f300196d90 OpcodeDispatcher: Optimize AddSubP{S,D} 
Use a named constant for loading the sign inversion, then EOR the second
source and just FAdd it all.
In a vacuum it isn't a significant improvement, but as soon as more than
one instruction is in a block it will eventually get optimized with
named constant caching and be a significant win.

Thanks to @rygorous for the idea!

Ryan Houdek bbf9cb9d52 IR: Implements new VRev32 and LoadNamedVectorConstant ops 
VRev32 matches Arm64 semantics directly.
LoadNamedVectorConstant allows FEX to quickly load "named constants".
This will allow us to have specific hardcoded vector constant values
that we can load with a ldr(State)+ldr(Value) and will be more abused in
the future.
This also allows us to do a very simple optimization in the future where
we can optimize away redundant loads of these loads if they are used
multiple times in the same block. (Not implemented here).

Alyssa Rosenzweig af21b8f3c7 Move External/FEXCore/ to FEXCore/ 
It is not an external component, and it makes paths needlessly long.
Ryan seemed amenable to this when we discussed on IRC earlier.
