Change parameters to language_defn::post_parser

Browse source 
In the expression rewrite, Ada type resolution will be done at parse
time rather than in a post-parse pass.  At this point,
language_defn::post_parser will be removed.  However, for this to
work, the information available to post_parser must be made available
during the actual parse.

This patch refactors this code slightly to make this possible.  In
particular, "void_context_p" is passed to the parser_state
constructor, and the parser state is then passed to the post_parser
method.
