690b491af1 fix loop bug in DispatchAlpha() 
* We were re-doing most of the work in plain-C as 'left-over'.
* we were always returning has_alpha = true because of a bad mask all_0xff

These bugs were conservative and silent, in the sense that we were 'just' doing
more work than necessary.

Now, the SSE2 version is really 2x faster than the C version.
