This reverts upstream commit fd484be:
Atomics cleanup (#11)
We need to test exception specifiers but they're gone in C++17 so
compile the tests with an older version of the standard.
Rewrite the guard logic to be more idiomatic C++ and more
comprehensible and make sure that atomics are used where necessary.
It looks like there are some corner cases in the i386 and/or 32-bit
atomics handling, which can make __cxa_guard_acquire() hang in certain
situations.
