Could cp_parser_implicitly_scoped_statement be flattened to use 
cp_lexer_next_token_is, rather than CLNTI_not?  that'd read better.  I'd
suggest
  if(cp_lexer_next_token_is (parser->lexer, CPP_OPEN_BRACE))
    .. handle {...}
  else if (cp_lexer_next_token_is (parser->lexer (CPP_SEMICOLON))
    .. handle empty
  else
    .. handle implicitly scoped stmt

The C++ changes will be ok with that change.  Someone else will need to approve 
the C change (but it looks ok to me)
