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).

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.

Optimize extremely aggressively.
...
Tell GCC to optimize cold functions for size and stash them away in
a separate part of the binary. Put the simulate core, meanwhile, on
the hot path. Also, bump optimization to -O3 as we can now "afford"
to do so.
