Commit Message

Use double-word atomic intrinsics for recent Clang versions (gcc/x86.h)

Older clang versions have some bugs or limitations that prevent from
using double-word built-in atomic operations.

Note: even as of clang-4.0, there seems to be a bug in some
double-word built-in operation if Thread Sanitizer is used.
