tree-optimization/101925 - fix VN with reverse storage order
This fixes value-numbering breaking reverse storage order accesses
due to a missed check. It adds a new overload for
reverse_storage_order_for_component_p and sets reversed on the
VN IL ops for component and array accesses accordingly.
It also compares the reversed reference ops flag on reference
lookup.

(vn_reference_eq): Compare reversed on reference ops.
(reverse_storage_order_for_component_p): New overload.
(vn_reference_lookup_3): Check reverse_storage_order_for_component_p
on the reference looked up.
