Subject: Revert r227538, since it doesn't compile with clang at all (it
 doesn't allow the built-in operations to be redefined, at least not without
 excessive force).

Instead, just disable LLVM's support for atomic operations for now.
Nothing in either clang or the tablegen tools currently depends on it.

This still allows users of head built before r198344 to upgrade to
top-of-head seamlessly.
