0fe1c50e50 all: do standards compliant absdiff computation
This resolves implementation defined behavior, and also silences -Wabsolute-value in clang 3.5+.
Moreover, the generated asm is identical to before modulo nop padding.

723550d3ca avfilter/vf_hqx: optimize table init
5389024880 -> 1389386610 dezicycles

This surely can be optimized more, i just didnt want to cause a slowdown
when trying to make the fate test bitexact.
Further optimization left to ubitux

This is useful to understand how it's different from the original code.
