Eliminate the duplicate functionality,
and better testing for the bench builders.

Things were running suspiciously well...
_I32 had a typo that cut out 3/4 of its multiplies...
_I32_SWAR was missing a mask operation needed to drop
the junk low byte of the high half after the multiply.
The bench times now make a bit more sense and are in line
with how much work we're actually doing: F32's the slowest,
I32 a little faster, and I32_SWAR fastest:

With all the thinking around a stack-based interpreter,
I figured I'd sketch out some ideas for a register VM too.
I kind of have the hunch that this is the direction that
will actually let us replace large amounts of Skia's CPU
backend with an efficient interpreter or JIT.
