7262516636 Start merging RSP vector functions. 
No need to separate all these functions when they contain so
much common code, so start combining things for the sake of
locality and predictor effectiveness (and size). In addition
to these benefits, the CPU backend is usually busy during the
execution of these functions, so suffering a misprediction
isn't as painful (especially seeing as we can potentially
improve the prediction from the indirect branch).

2de77746e7 Disable register caching for now. 
Until we can work around system libraries stomping over the
registers we want to reserve, just disable register caching for
the time being.

54c79ebc73 Hacky fix to patch register caching. 
On Windows, acc_lo (%xmm5) was clashing with the x64 calling
convention, which states %xmm5 is a volatile register and is
the caller's responsibility to save. We need the register
preserved across calls, so until we have a better solution to
the problem, pick registers that are not volatile according to
the calling convention.

b8fb829e1c Prevent register-caching on MinGW. 
Since Microsoft decided to totally bork their x86_64 calling
convention, defer all Windows builds to non-optimized RSP
routines. When MinGW supports __vectorcall, this change can
be reverted.

9077006d24 Only use VEX-encoded SSE where it helps us. 
Otherwise, stick to the "legacy" SSE instructions as they're
smaller and we don't use the upper halves of AVX registers
anyways.

ed1e354c68 Change RSP calling convention. 
pblendvb needs the mask in %xmm0, so change the calling convention
around just enough so we can cut out a movdqa from most instructions.
