rsp_veq_vge_vlt_vne optimization patch from izy.
...
mm: Might be better to fold these indirect branches back
into the RSP vector function table if we're going to ask
the compiler to generate a jump table here.

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).

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.
