[Clang] Fix compare-record.c test on s390x (NFC)

s390x looks through pointers when determining the "externally
visible vector ABI". For that reason, the test shows different
behavior just on that platform.

Adjust the test in the reverse direction of what I originall did:
Make sure that the type behind the pointer is always queried, by
dereferencing the pointer.
