Use GCC's implementation of atomicIncrement/Decrement on Mac
https://bugs.webkit.org/show_bug.cgi?id=106976
Reviewed by Filip Pizlo.
* wtf/Atomics.h:
GCC and LLVM have builtin for atomic ADD and SUB: __sync_add_and_fetch,
__sync_sub_and_fetch.
Using them let the compiler just generate the atomic operations inline
instead of generating a function call to LibC. It also simplify the
code a bit.
