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.

gcc/
* 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.
