Convert the QString::SplitBehavior variants to call them, rather than

Use QStringIterator rather than indexed loops. This fixes handling of
non-BMP code points (which may be lower or uppercase, see the test).
Change also the semantics of the functions, adopting Unicode §3.13
definitions: a string is lowercase/uppercase if it's equal to its
own toLower/toUpper folding.
As a side effect, empty strings are now correctly reported to be
lowercase AND uppercase.
[ChangeLog][Important Behavior Changes] The semantics of
QString::isLower() and QString::isUpper() have been changed to match the
Unicode specification. Now lowercase (resp. uppercase) strings are
allowed to contain any character; a string is considered lowercase
(resp. uppercase) if it's equal to its own toLower() (resp. toUpper())
folding. Previously, a non-letter character would make the string not
lowercase nor uppercase, and the mere presence of an uppercase (resp.
lowercase) letter would make isLower() (resp. isUpper()) return false,
even if the letter wouldn't change under case folding. As a
consequence, now empty strings are lowercase and uppercase.
[ChangeLog][QtCore][QString] Fixed a number of bugs of
QString::isLower() and QString::isUpper(). Empty strings are now
correctly reported to be lowercase (resp. uppercase), and strings
containing code points outside the BMP are now correctly handled.
Note that the behavior of these functions has also been changed.

The expression "a + offset + N" will eventually calculate an address
past the end of a, since we are comparing to end. That's undefined
behavior. Instead, calculate end - a and compare that to offset + N.
This commit subtracts "a" from both sides of the inequalities and swaps
the two sides to make them obey Qt coding style. Testing with GCC 9
(which is the only one I care about) shows the compiler generates the
same code.

QString(View)s can be built or manipulated in ways that make them
contain/refer to improperly encoded UTF-16 data. Problem is,
we don't have public APIs to check whether a string contains
valid UTF-16. This knowledge is precious if the string is to be fed in
algorithms, regular expressions, etc. that expect validated input
(e.g. QRegularExpression can be faster if it can assume valid UTF-16,
otherwise it has to employ extra checks).
Add a function that does the validation.
[ChangeLog][QtCore][QStringView] Added QStringView::isValidUtf16.

The SSE code can read slightly outside the bounds of the string.
This is ok, as it's limited to 16 byte boundaries and thus can't
cause a segfault. But it does cause a crash with asan.

The call to data() on a non-const QString led to a detach(), which is
unexpected and unwanted from QString::lastIndexOf() const.
Found by looking at why QFileSystemEntry::fileName() was expensive, in
the hotspot profiler.
The solution is to instanciate QLastIndexOf with QStringView() rather
than QString(). I added a deleted QString overload to make sure nobody
ever instanciates it with a QString argument again.

I'd have preferred to use QArrayDataPointer<ushort> for QString, but
that option wasn't the best one. QArrayDataPointer try to do some
operations using QArrayDataOps and that would expand to unnecessary
code. What's more, the existing code expected to be able to modify and
access the d pointer.
Instead, this commit introduces QStringPrivate (named differently from
QStringData to catch potential users), which contains the three
members. This POD class is also used in QJsonValue to store the
"inlined" QString. QHashedString in qtdeclarative will need a similar
solution.

Ported QArrayDataPointer & SimpleVector to the inlined size & data.
For now, the size and offset members are not yet removed from

Instead of using the reference count to store whether the data is
sharable and whether the header is immutable, move the settings to the
flags member. This allows us to save one comparison per deref() or
needsDetach(). It also allows for the possibility of mutable data
pointed to by a static header.

The Mutable flag now contains the information on whether the data this
QArrayData points to is mutable. This decouples the mutability /
immutability setting from the allocation and from the type of data,
opening the way for mutable raw or foreign data.
There are still plenty of places in the source code that check the
size of the allocation when it actually wants d->isMutable(). Fixing
this will require reviewing all the code, so is left for later.
The needsDetach() function is moved to QArrayData and
de-constified. It returns true when a reallocation is necessary if the
data is to be modified.

These flags allow us to determine what type of data QArrayData is
carrying. There are currently only two supported types:
- raw data type: constructed via fromRawData or static data
- allocated data type: regular data done via heap allocation
The QArrayData object is usually allocated on the heap, unless its own
reference count is -1 (indicating static const QArrayData). Such
object should have a type of RawDataType, since we can't call free().
Add GrowsBackward for completeness as well as the StaticDataFlags
default for static data.

In almost all cases, use d->allocatedCapacity() or
d->constAllocatedCapacity() instead of d->alloc, since they do the
same thing (right now). In the future, the functions will be
changed. There is a separate const version because most const code
should not need to know the allocation size -- only mutating code
should need to know that
There are a few cases where d->alloc was replaced with a better
alternative, like d->size. The one case that remains in the code will
be replaced by a different test when it's available.

being in the array itself, instead of used just for allocating new

For that reason, rename QArrayData::Default to

Also rename QArrayData::Grow to GrowsForward, so we may add

The assumption when calling QStringRef::toString() on a null
QStringRef (i.e. when QStringRef::isNull() is true) is that
QStringRef::toString().isNull() will also return true. With the
current implementation we return a null QString() only when the
QStringRef references a nullptr QString. We need to do the same
also when QStringRef references a QString with null private data.

Instead of four pairs of :1 :15 bit fields, use an array of four :1,
:15 structs. This allows to replace the case folding traits classes
with a simple enum that indexes into said array.
I don't know what the WASM #ifdef'ed code is supposed to effect (a :0
bit-field is only useful to separate adjacent bit-field into separate
memory locations for multi-threading), but I thought it safer to leave
it in, and that means the array must be a 64-bit block of its own, so
I had to move two fields around.
