Remove early-out from color analysis pass.

This early-out was a useful optimization when the passed-in count could
be large, but the analysis pass only takes 1-2 inputs nowadays, so it
doesn't add value. (Even if we did have a lot of inputs, most of the
checks in this loop correspond directly to a flag-bit check on an FP;
they aren't expensive either way.)

Also, did some minor polish/variable renaming for readability.
