> struct avr_builtin_description gets a new field .fndecl which is
> initialized during avr_init_builtins and looked up in new hook
> The built-ins are initialized in such a way that there is always
> avr_bdesc[x].id == x
> i.e. .id is superfluous and avr_expand_builtin can use id to access
> the array and need no search loop to find built-in id.
> PR target/52692
> * config/avr/avr.c (TARGET_BUILTIN_DECL): New define.
> (avr_builtin_decl): New static function.
> (struct avr_builtin_description, avr_bdesc): Move up.
> Add GTY marker. Add field fndecl. Remove redundant field id.
> (avr_init_builtins): Initialize avr_bdesc[ID].fndecl.
> (avr_expand_builtin): Code cleanup because .id is removed.
> * gcc.target/avr/torture/builtins-2.c: New test.
