This is caused by the big Ada patch that introduced the extra 2 ARRAY_REF
arguments. Unfortunately, I couldn't find the reason why is the last
ARRAY_REF's argument measured in aligment units and not in bytes
(and what was the reason for adding this argument).
The size_zero_node in last ARRAY_REF's argument is created in
gimplify.c (canonicalize_addr_expr), because the element type has
TYPE_ALIGN_UNIT 16, but TYPE_SIZE_UNIT 4, therefore it is 0 strides and
when array_ref_element_size multiplies it again by TYPE_ALIGN_UNIT, the result
is 0 and not 4.
