c485c835fe avutil/crc: Dont limit CRC32 standard tables 
Currently, standard tables like AV_CRC_32_IEEE and such are being generated (or
provided in case the user compiles with hardcoded tables) with only 257 elements.
We're missing a considerable boost in performance by not making them with a size
of 1024 elements instead.

cf6ed1f129 lavu/opencl: remove semi-colon from macro. 
Fixes compilation when the macros are empty and the label above ends up
containing no statement. Also makes usage of these macro consistent
(some already have a semi colon, some others don't).

d0a34aeedf md5: optimize second round by using 4-operation form of G() 
4-operation form is preferred over 3-operation because it breaks a long
dependency chain, thus allowing a superscalar processor to execute more
operations in parallel.
The idea was taken from: http://www.zorinaq.com/papers/md5-amd64.html
