Log Message:
lint: add support for C11 '_Atomic' as atomic-type-specifier

Following the C11 grammar, the keyword '_Atomic' needs to be a separate
syntactic category, to avoid further conflicts in the grammar.

The two newly added conflicts in the grammar would come into play when
mixing traditional C with C11, in a type name without an implicit 'int'.
If the type '_Atomic(int)*' were parsed as '_Atomic int(int)*', the
trailing '*' would be a syntax error.
