Subject: [PATCH] [C] Add C11 _Atomic type qualifier and specifier (#4080)

This was originally added in C11. It is an optional feature but
is often available due to being related to threads. It can be
as a type qualifier like const or as a type specifier like typeof.
It is implemented under both syntax rules to reflect this.
