The patch looks correct as far as it goes.

Instead of making _Complex_I a keyword, you could just #define it to
the GNU equivalent in the predefines; it's not precisely correct, but
it's a lot less work to get it working.  If you want to get it working
cleanly, I guess the next step would be making
Parser::ParseCastExpression actually handle _Complex_I, then adding an
AST node, then adding Sema and CodeGen handling.
