MIPS: Tighten the code for MacroAssembler::ThrowUncatchable.

MIPS: Tighten the code for MacroAssembler::ThrowUncatchable.

Port r9909 (56c8728aa).

Original commit message:
Test at the bottom in the unwind loop.  Eliminate the possibility of a
useless move to the eax/rax/r0 register (currently impossible because
this function has two call sites).  Do not explicitly zero the context
because we've already saved 0 as the context in the handler.

Indentation was off here, I'll fix it.
