The LDAXR/STLXR sequences rely on the C11/C++11 prohibition of data races.
That the __atomic builtins assume this restriction is implied by

The switch statement in loc_list_from_tree
doesn't handle DEBUG_EXPR_DECL which is why it ICEs.
However, I'm not familiar with the code.
Should it handle DEBUG_EXPR_DECL (just return 0)?
