* gfortran.h : Add fn_result_spec bitfield to gfc_symbol.
* resolve.c (flag_fn_result_spec): New function.
(resolve_fntype): Call it for character result lengths.
* symbol.c (gfc_new_symbol): Set fn_result_spec to zero.
* trans-decl.c (gfc_sym_mangled_identifier): Include the
procedure name in the mangled name for symbols with the
fn_result_spec bit set.
(gfc_finish_var_decl): Mark the decls of these symbols
appropriately for the case where the function is external.
(gfc_get_symbol_decl): Mangle the name of these symbols.
(gfc_create_module_variable): Allow them through the assert.
(gfc_generate_function_code): Remove the assert before the
initialization of sym->tlink because the frontend no longer
uses this field.
* trans-expr.c (gfc_map_intrinsic_function): Add a case to
treat the LEN_TRIM intrinsic.
(gfc_trans_string_copy): Deal with Wstringop-overflow warning
that can occur with constant source lengths at -O3.
