poly_int: frame allocations
This patch converts the frame allocation code (mostly in function.c)
to use poly_int64 rather than HOST_WIDE_INT for frame offsets and
sizes.

* function.h (frame_space): Change start and length from HOST_WIDE_INT
to poly_int64.
(get_frame_size): Return the size as a poly_int64 rather than a
HOST_WIDE_INT.
(frame_offset_overflow): Take the offset as a poly_int64 rather
than a HOST_WIDE_INT.
(assign_stack_local_1, assign_stack_local, assign_stack_temp_for_type)
(assign_stack_temp): Likewise for the size.
* function.c (get_frame_size): Return a poly_int64 rather than
a HOST_WIDE_INT.

than a HOST_WIDE_INT.
(try_fit_stack_local): Take the start, length and size as poly_int64s
rather than HOST_WIDE_INTs. Return the offset as a poly_int64_pod
rather than a HOST_WIDE_INT.

HOST_WIDE_INTs.

(expand_stack_vars, expand_one_stack_var_1, expand_used_vars): Handle
polynomial frame offsets.
