fd5fd48659 libavcodec/mips: Fix build errors reported by clang
Clang is more strict on the type of asm operands, float or double
type variable should use constraint 'f', integer variable should
use constraint 'r'.

d5380f068d libavutils: Add parse_r helper for MIPS
That helper grab from kernel code can allow us to inline
newer instructions (not implemented by the assembler) in
a elegant manner.

a251aa1a35 mips/asmdefs: use _ABI64 as defined by gcc
Unfortunately android < api 21 (lollipop) doesn't have the sgidefs.h header,
the easiest way around this is to just use the preprocessor definitions from
gcc / clang.

157d6f0d5b mips: port optimizations to mips n64
This mainly consists of replacing all the pointer arithmatic 'addiu'
instructions with PTR_ADDIU which will handle the differences in pointer
sizes when compiled on 64 bit mips systems.

The header asmdefs.h contains the PTR_ macros which expend to the correct mips
instructions to manipulate registers containing pointers.
