0ace686ae8 avcodec: optimize mathops for Loongson-3 v1
HAVE_LOONGSON is replaced by HAVE_LOONGSON3. Even Loongson-2E and 2F support
Loongson SIMD instructs but have low performance for decoding. We plan to focus
on optimizing Loongson-3A1000, 3B1500 and 3A1500, and modify the configure file
to support Loongson-2 series later by adding HAVE_LOONGSON2.

213e823dc6 mips/mathops: remove 64-bit code
GCC is perfectly happy generating optimized multiplication code on its own for
64-bit arches. GCC refuses to optimize the loongson code when in 32-bit mode,
so I've left that.
