* language.h (language_defn): Add new la_post_parser field.

Browse source 
* parser-defs.h (null_post_parser): New declaration (default for
la_post_parser).

* parse.c (parse_exp_1): Move code to parse_exp_in_context and
insert call to that function.
(parse_exp_in_context): New function, including code formerly in
parse_exp_1.  Calls language-dependent post-parser after
prefixification.
(parse_expression_in_context): New exported function.
(null_post_parser): New definition.
* expression.h (parse_expression_in_context): Add declaration.

* p-lang.c (pascal_language_defn): Add trivial post-parser.
* c-lang.c (c_language_defn): Ditto.
(cplus_language_defn): Ditto.
(asm_language_defn): Ditto.
(minimal_language_defn): Ditto.
