* emit-rtl.c (adjust_address_1): Do not drop the object
if the new memory reference is outside the underlying
object to preserve object attributes that are needed
by some backend implementations. Remove adjust_object
parameter as it is not used anymore.
(adjust_automodify_address_1): Adjust according to
new adjust_address_1 prototype.
(replace_equiv_address_nv): Likewise.
* gcc/emit-rtl.h (adjust_address): Adjust according to
new adjust_address_1 prototype.
(adjust_address_nv): Likewise.
(adjust_bitfield_address): Likewise.
(adjust_bitfield_address_size): Likewise.
(adjust_bitfield_address_nv): Likewise.
