deciding whether to propagate to descendants. This lead to a
QDateTimeEdit's calendar popup not getting told what locale to use

Commit e0ea0f6178 optimized QChar <->
QString(Ref) comparisons by adding more overloads to avoid creating
QStrings from QChars just to compare them.
But these new overloads made existing comparisons to QChar ambiguous.
This was known at the time for QChar/int comparisons.
It has since turned out that also comparing to '\0' is ambiguous,
ie. not comparing to int or char per se is ambiguous, but comparing to
nullptr constants is, because QString(const char*) is just as good a
candidate as QChar(char)/QChar(int).
Since we allow QString/QChar comparisons, it seems logical to solve
the problem by adding QChar<->nullptr overloads.
[ChangeLog][QtCore][QChar] Disambiguated comparisons with nullptr
constants such as '\0', which 5.8.0 broke. As a consequence,
QChar<->int comparisons are no longer deprecated, as this was a failed
attempt at fixing the ambiguity.

Timer IDs have been reused since Qt 4.5 or thereabouts, so just checking

timer may have been deleted and replaced by another with the same ID.
Instead of deleting the WinTimerInfo object, let's just mark it as
unregistered by setting timerId to -1 and cooperate in deleting at the
appropriate places. Since unregisterTimer skips deleting if inTimerEvent
is true, the appropriate places are everywhere that set inTimerEvent to
true.

Commit fb376e0fcc removed an array that
facilitated returning the names of built-in types, to avoid the jump tables
from the switch statement. This commit brings it back but makes the array a
compile-time constant string offset table.
The array is created by way of a set of C++11 constexpr functions, so we
require that compiler feature. I've tested that MSVC 2015 does support
it as well as the ICC 17 when masquerading as MSVC 2015, so I've enabled
for that too. The only compiler left out is MSVC 2013.
If we didn't need to support MSVC 2015, this could have been written
more simply with C++14 relaxed constexpr.
This also adds unit tests to confirm that QMetaType::typeName() does
return null when we said it would. We're testing QMetaType::User-1
(which we'll likely never use) and QMetaType::LastWidgetsType-1 to
select something inside the range of the built-in types.
