Some function had exceed 30 inline assembly register oprands limiation
when using LOONGSON2 version of MMI macros. We can avoid that by take
$at, which is register reserved for assembler, as temporary register.
As none of instructions used in these macros is pseudo, it is safe to
utilize $at
Loongson3's extention instructions (prefixed with gs) are widely used
in our MMI codebase. However, these instructions are not avilable on
Loongson-2E/F while MMI code should work on these processors.
Previously we introduced mmiutils marcos to provide backward compactbility
but newly commited
{SAVE,RECOVER}_REG will be available for Loongson2 again,
also comment about the magic.

According to the latest instruction mannual, we should use 'pxor' but not 'xor'

Use avfilter_graph_alloc() instead of av_mallocz(sizeof(AVFilterGraph))
to allocate an AVFilterGraph; this also properly allocates the graph's
internal. The current code just happened to work because it did not
make any use of said internal.
Also check the allocation; this fixes Coverity
