This class is very expensive to initialize so if you happen to have the
disassembler configuration enabled you were eating a very bad
initialization cost for no reason.
Only initialize the data member if any disassembler runtime option is
enabled, this completely removes the overhead.
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).
It is not an external component, and it makes paths needlessly long.
Ryan seemed amenable to this when we discussed on IRC earlier.
