Bring in WebKit revisions 139553 and 139921.
They are primarily useful for getting rid of some libstdc++-specific
includes which break the build with libc++, and also for simplifying the
code and removing a Darwin-specific code path.
r139553 by ossy@webkit.org:
Use sync_add_and_fetch instead of gnu_cxx::exchange_and_add
https://bugs.webkit.org/show_bug.cgi?id=106729
After r139514 we need atomicIncrement(int64_t volatile*) for all
platform. Now the GCC implementation of atomicIncrement() is based on
gnu_cxx::exchange_and_add, which doesn't support int64_t type, but
sync_add_and_fetch does.

r139921 by benjamin@webkit.org:
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.
