re PR middle-end/37774 (Alignment information is lost for ARRAY_REFs)
PR middle-end/37774
* tree.h (get_object_alignment): Declare.
* emit-rtl.c (set_mem_attributes_minus_bitpos): Call
get_object_alignment if needed.
* builtins.c (get_pointer_alignment): Move ADDR_EXPR operand handling
to ...
(get_object_alignment): ... here. New function. Try harder to
determine alignment from get_inner_reference returned offset.
