[PATCH] c: Fix up uninitialized next.original_type use in #embed optimization

[Jakub Jelinek]

Hi!

Jonathan pointed me at a diagnostic from an unnamed static analyzer
which found that next.original_type isn't initialized for the CPP_EMBED
case when it is parsed in a comma expression, yet
  expr.original_type = next.original_type;
is done a few lines later and the expr is returned.

Fixed thusly, tested on x86_64-linux, ok for trunk?

        * c-parser.cc (c_parser_expression): Initialize next.original_type
        to integer_type_node for the CPP_EMBED case.
