poly_int: MACRO_MODE
This patch uses a MACRO_MODE wrapper for the target macro invocations
in targhooks.c and address.h, so that macros for non-AArch64 targets
can continue to treat modes as fixed-size.
It didn't seem worth converting the address macros to hooks since
(a) they're heavily used, (b) they should be probably be replaced
with a different interface rather than converted to hooks as-is,
and most importantly (c) addresses.h already localises the problem.

gcc/
* machmode.h (MACRO_MODE): New macro.
* addresses.h (base_reg_class, ok_for_base_p_1): Use it.
* targhooks.c (default_libcall_value, default_secondary_reload)
(default_memory_move_cost, default_register_move_cost)
(default_class_max_nregs): Likewise.
