Add code to demangle and cache C++ symbol names. Use macro form if INLINE_ADD_PSYMBOL is true, otherwise use C function form. * symmisc.c (add_psymbol_to_list, add_psymbol_addr_to_list): Remove, also defined in symfile.c, which we already fixed. * symtab.c (expensive_mangler): Remove prototype and function. * symtab.c (find_methods): Remove physnames parameter and fix prototype to match. * symtab.c (completion_list_add_symbol): Name changed to completion_list_add_name. * symtab.c (COMPLETION_LIST_ADD_SYMBOL): New macro, adds both the normal symbol name and the cached C++ demangled name. * symtab.c (lookup_demangled_partial_symbol, lookup_demangled_block_symbol): Remove prototypes and functions. * symtab.c (lookup_symbol): Remove use of expensive_mangler, use lookup_block_symbol instead of lookup_demangled_block_symbol.
