Andrey Semashev d42a407bb3 Use intrinsics in gcc sync backend to load and store large objects. ...

There is no guarantee of atomicity of plain loads and stores of anything
larger than a byte on an arbitrary hardware architecture. However, all
modern architectures seem to guarantee atomicity of loads and stores of
suitably aligned objects ate least up to a pointer size, so we use that
as the threshold. For larger objects we have to use intrinsics to
guarantee atomicity.
