* buildsym.c (end_symtab): Remove sort_pending and sort_linevec

        arguments.  Sorting is now dependent on OBJF_REORDERED.  All
        callers/references changed.
        * dbxread.c (read_ofile_symtab): Correctly determine value for
        last_source_start_addr for reordered executables.
        (process_one_symbol): Handle N_FUN with no name as an end of
        function marker.
        * partial-stab.h (case N_FN, N_TEXT): Don't assume CUR_SYMBOL_VALUE
        is the high text address for a psymtab.
        (case N_SO): Likewise.
        (case N_FUN): Handle N_FUN with no name as an end of function
        marker.
        * minsyms.c (lookup_minimal_symbol_by_pc): Examine all symbols
        at the same address rather than a random subset of them.
        * coffread.c (coff_symfile_init): Set OBJF_REORDERED.
        * elfread.c (elf_symfile_init): Similarly.
        * somread.c (som_symfile_init): Similarly.
        * xcoffread.c (xcoff_symfile_init): Similarly.

Support for debugging reordered executables.  Remaining mentor vm
changes.
