cc1: Fix check of duplicated macro parameter

When the code changed to use the tokenizer we didn't realize that
the check for duplicated parameter was using yytext, but in  one
of the cases we were calling next() that invalidated the use of
yytext. Also, the new namespace added for macro parameters had to
be used instead of the generic NS_IDEN used before. Thankfully
one of the error tests catched  this error.
