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.

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.
