Loading pb_1 rather than pw_8192 was benchmarked to be more efficient.
Loading of the 2 yields no advantage. Loading of one saves ~11 cycles.

Currently, only the mmx version is bitexact, the others (mmxext and
3dnow) are not, in spite of their naming.
Therefore, make their name more obvious. Also restore a comment that
was removed in 71155d7b.

The mmxext optimizations should be at least equally fast if available and
amd3dnow optimizations are being deprecated. Thus the former should
override the latter, not the other way around.
