Struct Quals 

pub struct Quals(/* private fields */);

The type qualifiers, as a set.

_Atomic is here because it can be written in qualifier position, where it qualifies whatever the declarator arrives at. _Atomic(T), with parentheses, is a different thing and is TypeSpec::Atomic, because it constructs a type that may not have the same alignment as T. Both spellings mean the same in the end and the difference matters to the parser.
