ffmpeg | branch: master | Michael Niedermayer <michaelni at gmx.at> | Wed Jan 11 20:42:23 2012 +0100| [05577aafaa75e255a140cd8454fd7c8cffa67965] | committer: Michael Niedermayer

sws: yuv2rgb asm, add memory clobber.

This fixes dithering for rgb555le, it appears gcc had moved the
setup of the variables after the asm or something like that.
