Revert "lavu/atomic: add support for the new memory model aware gcc built-ins"
This reverts commit faa9d2982969c999ab0e443a226eff116f7f8e4b.
This change became superfluous when support for C11 atomics was introduced.
Reverting it will make the removal of this implementation in an upcoming
merge conflict free.
