The GCC model for extended instructions like these is that you compile
with -msse3 etc. These affect code generation for whole compilation units,
so the idea is that you have a separate .c file for each instruction set
class and then indirect to the desired one at runtime.
Without e.g. -msse4.1, the GCC built-ins used by <foointrin.h> are not
available. However, in our specific case of compiling with -msse2 and
wanting to use SSE3.1 code, enough built-ins are available that we only
need to provide a little hack for pshufb.
Upgrading this to also use SSE4.1 instructions doesn't appear feasible
without a lot of undesirable duplication of GCC built-in functions and
headers, so we'd probably have to move to the GCC model of separate
source files for that.

Because we only ever call Pos_ReadDirect (and through that, DataRead<T>)
from JIT generated code, the compiler may not get the heads-up to properly
prepare for run-time instantiation of those template functions.
Explicitly instantiating Pos_ReadDirect gets around that issue.
Also force DataRead* inline as gcc didn't always do that itself when the
DataRead functions in turn were called from (other) template functions.

sorry to tell but this will bring a speed drop, so let you decide if this change stay or not.( used the fastest open source hash algorithm i know)
do not apply full hashing to other format because it kills the performance.
for popular request added 9x SSAA believe me will kill your graphic card even if is the best but the image quality is exceptional.
as always please test and let me know the results.

Highlight differences on both sides.
Show the accelerator subregs in order.
Make it possible to include some code from Dolphin into DSPSpy, good for grabbing useful #defines. (had to change the GEKKO log to POWERPC).

Not really anything interesting, just some better comments, some slightly more portable/cleaner code in places.
