    PR10327: resolve symbol aliases to dwarf functions
    
    This will first read in the symbol table for modules, and update the
    dwarf cu_function_cache with aliased names too.  Then when iterating
    in dwarf, all of the possible names are matched, instead of only the
    canonical dwarf name.
    
    * dwflpp.cxx (dwflpp::iterate_over_functions): call update_symtab,
      and track wildcard addresses in a set to avoid alias dupes
    * dwflpp.h (symbol_table::Compare): removed
    * tapsets.cxx (symbol_table::map_by_addr): replaces list_by_addr
      (symbol_table::sort): removed -- multimap doesn't need sorting
      (symbol_table::mark_dwarf_redundancies): removed, see update_symtab
      (symbol_table::purge_syscall_stubs): remove map elements inline
      (dwarf_query::handle_query_module): preload the symtable.
      (query_dwarf_func): don't compare the function a second time,
      especially since it may have been an alias that matched at first.
      (module_info::get_symtab): allow being called multiple times
      (module_info::update_symtab): copy dies from the cache to the symtab,
      and also add aliased names to the cache
