    avcodec/snowdata: Don't use 8 bits for six bits data
This has been done in 561a18d3ba07382dffdf583dda13f6954109b116
in order to avoid shifts, yet this rationale no longer applies
since d593e329832a432777218eb92469bad10594a3c5. So shift them back;
this is in preparation for using these coefficients together with
pmaddubsw.

Hint: 561a18d3ba07382dffdf583dda13f6954109b116 also added a block
guarded by "if(LOG2_OBMC_MAX == 8". I changed the condition to remove
this check (i.e. kept the block) which should not change the output
at all. Yet all FATE tests pass if the block is completely
removed. I don't know if this block is necessary at all.

    avcodec/snow: Avoid always-true branch
The input lines used in ff_snow_inner_add_yblock()
must always be set (because their values are used).
The MMX assembly always relied on this.

    tests/checkasm: Add snowdsp test
Only inner_add_yblock for now.
Hint: Said function uses a pointer to an array of pointers as parameter.
The MMX version clobbers the array in such a way that calling the
function repeatedly with the same arguments (as happens inside bench_new())
leads to buffer overflows and segfaults. Therefore CALL4 had to be
overridden to restore the original pointers. This workaround will be
removed soon when the MMX version is removed.

The first loop was never entered due to a precedence problem;
the second loop initialized everything, although it was not intended
that way.

    avcodec/x86/snowdsp: Add SSSE3 inner_add_yblock
Compared to the MMX version, this version benefits from wider
registers and pmaddubsw. It also has fewer unnecessary loads
and stores: On x64, the MMX version has 12 unnecessary GPR loads
and 6 stores in each line when width is eight; for width 16,
there are 17 unnecessary GPR loads and six stores per line.
Even the 32bit SSSE3 version only has six loads and zero stores
per line more than the x64 version. Furthermore, in contrast
to the MMX version, the SSSE3 version also does not clobber
the array of block pointers given to it.

Benchmarks:
inner_add_yblock_2_c:                                   29.2 ( 1.00x)
inner_add_yblock_2_mmx:                                 32.5 ( 0.90x)
inner_add_yblock_2_ssse3:                               28.6 ( 1.02x)
inner_add_yblock_4_c:                                   85.2 ( 1.00x)
inner_add_yblock_4_mmx:                                 89.2 ( 0.96x)
inner_add_yblock_4_ssse3:                               84.5 ( 1.01x)
inner_add_yblock_8_c:                                  302.0 ( 1.00x)
inner_add_yblock_8_mmx:                                 77.0 ( 3.92x)
inner_add_yblock_8_ssse3:                               30.6 ( 9.85x)
inner_add_yblock_16_c:                                1164.7 ( 1.00x)
inner_add_yblock_16_mmx:                               260.4 ( 4.47x)
inner_add_yblock_16_ssse3:                              82.3 (14.15x)

Both the MMX and SSSE3 versions leave the size 2 and 4 cases
to ff_snow_inner_add_yblock_c() (but the MMX version has
a prologue at the beginning that it needs to undo before
the call, leading to the higher overhead for these sizes).
I don't know why the SSSE3 version is marginally faster than
the C version in these cases.
