Andreas Rheinhardt a79bfc2222 swscale/x86/swscale: Fix undefined left shifts of negative numbers

This affected many FATE-tests: The number of failing tests went down
from 663 to 344. (Both numbers exclude tests that failed because of
unaligned accesses in code that is inside #if HAVE_FAST_UNALIGNED.)
