Improve output on test failures
This adds checks to ensure Q_ALIGNOF is returning the desired alignment
for explicitly-aligned types.
The alignment check is now inlined in the test inside QCOMPARE so we get
slightly more informative errors:
FAIL! : tst_Collections::alignment() Compared values are not the same
Actual (quintptr(&it.value()) % Value::PreferredAlignment): 64
Expected (quintptr(0)): 0
Loc: [tst_collections.cpp(3384)]
In this case, this is enough to notice "non-native" alignments are being
requested. Having test parameters otherwise hidden in template arguments
doesn't help the situation.
