volatile array field is copied.
The crash occurs because method 'visitArray' passes a null FieldDecl to
method 'visit' and some of the methods called downstream expect a
non-null FieldDecl to be passed.
This reapplies r330151 with a fix to the test case.

setting the NonTrivialToPrimitive* flags of a record.
Union fields that have non-trivial Objective-C ownership qualifications
are normally not legal, but if the union is declared in a system header,
the fields are annotated with attribute "unavailable".

ARC mode.
Declaring __strong pointer fields in structs was not allowed in
Objective-C ARC until now because that would make the struct non-trivial
to default-initialize, copy/move, and destroy, which is not something C
was designed to do. This patch lifts that restriction.
Special functions for non-trivial C structs are synthesized that are
needed to default-initialize, copy/move, and destroy the structs and
manage the ownership of the objects the __strong pointer fields point
to. Non-trivial structs passed to functions are destructed in the callee
function.
