PTAL.

I’ve changed the register names to be more consistent with other mips64 usage,
but this is just a cosmetic change. (The MIPS64 port uses the n64 ABI, which
uses a0-a7 as arguments and t0-t3 for temp registers. In this case a4 is the
next available register. Since it is just a temp register, t1 would also be
fine.)
I've also changed kCompilerHintsOffset to kStrongModeByteOffset, which is more
endian-safe, although we only support little-endian mode on MIPS64.
