2768f7e4fe sparc: VIS mnemonics 
Currently, if VIS is enabled by configure, it will also be enabled at
run-time regardless of its support in the hardware. Thus, masking VIS
usage as it is done in vis.h by constructing binary instructions is
pointless. Using normal VIS mnemonics in inline assembly allows to take
advantage of automatic register allocation, gets rid of register
variables, which are unsupported by suncc for SPARC, and improves code
readability.

259af1b923 mpegvideo: allocate sufficiently large scratch buffer for interlaced vid 
MPV_decode_mb_internal needs 3 * 16 * linesize bytes of scratch buffer

For interlaced content, linesize is multiplied by two after the allocation
of the scratch buffer, and the dest_cr pointer ends past the buffer.

This patch makes ff_mpv_frame_size_alloc allocate a total of
(aligned line_size) * 2 * 16 * 3 bytes, which suffices even for the
interlaced case.
