Do a check first if we need to transform before doing the transform.
This means we won't detach when transforming data that is already
correct.
And instead of using QChar, use our own hand-rolled table. In a proper
LTO build, the QChar calls would be resolved to a lookup of the Unicode
data, but not many people do LTO builds, Therefore, this means a great
speed-up is achieved by simply avoiding the function call. The extra
gain in performance comes from the simpler translation table instead of
the more complex full-Unicode data.
Also as a consequence, this changes the handling of two characters in
Latin 1: 'ß' should be uppercased to "SS" but we won't do it, and 'ÿ'
can't be uppercased in Latin 1 ('Ÿ' is outside the range).
Benchmarking is included. Comparing the Qt 5.4 algorithm to the new code
is almost 20x faster. Other alternatives are included in the benchmark
and are all faster than the current code, though slower than the new
one. While all of them could compress the tables to be smaller or shared
between uppercasing and lowercasing, they would also expand to more code
(though probably less than the extra bytes required in the full
translation table). In the trade-off, I decided to go with simplicity
and most efficient code.

There were two constuctors offering essentially the same functionality.
One taking the QStatic*Data<N> struct, the other what essentially
amounts to a pointer wrapper of that struct. The former was dropped and
the latter untemplatized and kept, as that is the most generic and
widely applicable. The template parameter in the wrapper was not very
useful as it essentially duplicated information that already maintained
in the struct, and there were no consistency checks to ensure they were
in sync.
In this case, using a wrapper is preferred over the use of naked
pointers both as a way to make explicit the transfer of ownership as
well as to avoid unintended conversions. By using the reference count
(even if only by calling deref() in the destructor), QByteArray and
QString must own their Data pointers.
Const qualification was dropped from the member variable in these
wrappers as it causes some compilers to emit warnings on the lack of
constructors, and because it isn't needed there.
To otherwise reduce noise, QStatic*Data<N> gained a member function to
directly access the const_cast'ed naked pointer. This plays nicely with
the above constructor. Its use also allows us to do further changes in
the QStatic*Data structs with fewer changes in remaining code. The
function has an assert on isStatic(), to ensure it is not inadvertently
used with data that requires ref-count operations.
With this change, the need for the private constructor taking a naked
Q*Data pointer is obviated and that was dropped too.
In updating QStringBuilder's QConcatenable specializations I noticed
they were broken (using data, instead of data()), so a test was added to
avoid this happening again in the future.
An unnecessary ref-count increment in QByteArray::clear was also
dropped.

For data allocated and maintained by QByteArray, there's a guarantee
that data() is null-terminated. This holds true even for null and empty,
where logically the terminating character should never be dereferenced.
For tests that modify or generate QByteArrays, this ensures the
invariant is kept.
In the toFromHex() text, const-ness of temporary variables was dropped
to enable the test macro to be used, as the qualification didn't add
much to the test otherwise.

qAllocMore is used by growing containers to allocate additional memory
for future growth. The previous algorithm would grow linearly in
increments of 8 up to 64 and then progress exponentially in powers of
two.
The new (constant time) algorithm does away with the linear segment and
always progresses exponentially. It also has the nice benefit of cleanly
avoiding undefined behaviour that the old implementation tried hard to
circumvent.
Besides always progressing exponentially, the next-power-of-two
algorithm was tweaked to always include space for growth. Previously
queries at boundary values (powers of two) would return the same value.
The test was updated to verify sanity of results. As the algorithm is
well behaved, testing of bogus data was dropped. Whatever happens in
those cases is irrelevant, anyway: the bug lives elsewhere.
