Tom Tromey 69d340c684 Remove la_error
While working on the parser code, I noticed that yyerror is exported
from each parser.  It is used by this code in parse.c:

   TRY
     {
       if (lang->la_parser (&ps))
         lang->la_error (NULL);
     }

However, it seems to me that la_error will never be called here,
because in every case, la_parser throws an exception on error -- each
implementation of yyerror just calls error.

So, this patch removes la_error and makes all the yyerror functions
static.  This is handy primarily because it makes it simpler to make
the expression parsers pure.

Tested by the buildbot.
