[PATCH v2 06/14] Support for 64-bit location_t: Frontend parts

[Lewis Hyatt]

The C/C++ frontend code contains a couple instances where a callback
receiving a "location_t" argument is prototyped to take "unsigned int"
instead. This will make a difference once location_t can be configured to a
different type, so adjust that now.

Also remove a comment about -flarge-source-files, which will be removed
shortly.

gcc/c-family/ChangeLog:

        * c-indentation.cc (should_warn_for_misleading_indentation): Remove
        comment about -flarge-source-files.
        * c-lex.cc (cb_ident): Change "unsigned int" argument to type
        "location_t".
        (cb_def_pragma): Likewise.
        (cb_define): Likewise.
        (cb_undef): Likewise.
