Performance improvements:
quant_bands:
with: 681 decicycles in quant_bands, 8388453 runs,155 skips
without: 1190 decicycles in quant_bands, 8388386 runs,222 skips
Around 42% for the function
Twoloop coder:
abs_pow34:
with/without: 7.82s/8.17s
Around 4% for the entire encoder
Both:

Now that this function is SSE2 you should explicitly use
floating-point instructions to avoid bypass delays from transitioning
between int
