The Parser takes tokens read by the Lexer and assigns meaning to them.
It's responsible for determining what 'int' means, for example. The
parser uses this information to build the AST.

I understand your concern. Parts of Clang have me confused, too :). But
don't worry; there's plenty of people around here (including me) who are
willing to help you understand how Clang works.
