Fix the atomicIncrement implementation for MIPS GCC
https://bugs.webkit.org/show_bug.cgi?id=106739
Patch by Balazs Kilvady <kilvadyb@homejinni.com> on 2013-02-26
Reviewed by Oliver Hunt.
Implementation of missing __sync_[add|sub]_and_fetch_8 functions.
Some architectures, like MIPS32, don't have GCC implementation for
builtin __sync_* functions with 64 bits variable size. GCC answer
for the problem: If a target doesn't support atomic operations on
certain variable sizes, you are out of luck with atomicity in that
case (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56296). GCC >= 4.8
will support __atomic_* builtin functions for this purpose for all
the GCC targets, but for current compilers we have to include our
own implementation.
