Port the MIPS atomics to the new QBasicAtomicXXX architecture 

The LL/SC instructions are only present on MIPS II and up, so don't
pretend to support MIPS I. The previous implementation emitted the
instructions by telling the assembler to change instruction sets. Now,
the user must pass an -march= option to GCC telling it which
architecture or processor is being targetted.

On MIPS64, the 64-bit implementation allows supporting for long long
too.
