Optimize split MC, so we don't always do 4x4 blocks of 4x4pixels each, but
...
we apply them as 16x8/8x16/8x8 subblocks where possible. Since this allows
us to use width=8/16 instead of width=4 MC functions, we can now take more
advantage of SSE2/SSSE3 optimizations, leading to a total speedup for splitMV
filter of about 10%.

tablegen: implement and use WRITE_ARRAY macros
...
Two macros (WRITE_ARRAY and WRITE_ARRAY_2D) take the prefix (modifiers)
(not all tables are static, and they might not be constant either), the
type, and the name of the array. It'll be copied with same name and type,
and with the correct size of the currently-defined object.

tableprint: use the type name as-is for the functions' names.

This drops one parameter from the functions' macros, and require structures
