If QObjectPrivate::declarativeData is set, it is
in various places in Qt expected to point to a
QAbstractDeclarativeDataImpl, from which ownedByQml1
is unconditionally read.
In noDeclarativeParentChangedOnDestruction(), the
declarativeData pointer is, however, set to a local
QAbstractDeclarativeData instance, which, being an
empty class, has size 1 and alignment 1.
Depending on the compiler's idea of bit field order,
this code either read uninitialized data from the
dummy object, or else some random stack memory outside
any (valid) object.
What caught UBSan's attention, though, was the
difference in alignment between the two classes:
src/corelib/kernel/qobject.cpp:917:9: runtime error: member access within misaligned address 0x7fffc9cf706f for type 'struct QAbstractDeclarativeDataImpl', which requires 4 byte alignment
Fix by providing a properly initialized object of the
correct type.

When the byte sequence for a BOM occurs in the middle of a utf8 stream,
it is a ZWNBSP.
When a ZWNBSP occurs in the middle of a utf8 character sequence, and the
SIMD conversion does some work (meaning: the length is at least 16
characters long), it would not recognize the fact some charactes were
already decoded. So the conversion would then strip the ZWNBSP out,
thinking it's a BOM.
The non-SIMD conversion did not have this problem: the very first
character conversion would already set the headerdone flag.

To handle network events, QEventDispatcherWin32 uses I/O model
based on notifications through the window message queue. Having
successfully posted notification of a particular event to an
application window, no further messages for that network event
will be posted to the application window until the application
makes the function call that implicitly re-enables notification
of that network event. With these semantics, an application need
not read all available data in response to an FD_READ message:
a single recv in response to each FD_READ message is appropriate.
If an application issues multiple recv calls in response to a
single FD_READ, it can receive multiple FD_READ messages
(including spurious).
To solve this issue, this patch always disables the notifier
after getting a notification, and re-enables it only when the
message queue is empty.

Playing with the offset argument of pcre_exec is not equivalent to
adjusting the pointer to the subject string. In particular, PCRE
can go behind the offset to check for lookbehinds or "transition"
metacharacters (\b, \B, etc.).
This made the code that deals with QStringRefs not matching in behavior
with the corresponding code dealing with QStrings. For instance,
QString subject("Miss");
QRegularExpression re("(?<=M)iss");
re.match(subject.mid(1)); // doesn't match
re.match(subject.midRef(1)); // matches!!!
Instead, actually adjust the pointer to the subject string so that
the behavior is identical. A broken test that relied on the
equivalence is also removed.
