The returned data is in US-ASCII (or else Latin-1), and resides in
consecutive memory. We can therefore return it in a QLatin1String,
which, however, will in general not be NUL-terminated.
Many users use the return value as part of a QStringBuilder
expression, and those which are not are not pessimized further by
this change.
The caller in qtimezoneprivate_icu looks as if it could simply zero
-terminate the return value and use it as-is, as opposed to
converting to UTF-8, but I left the code equivalent to the original
just the same.

QStringView is a simple container for (const QChar*, int) and (const
char16_t*, size_t). It acts as a replacement interface type for const
QString and const QStringRef, and enables passing all kinds of
string-like types to functions otherwise expecting const QString& -
without the need to convert to QString first.
The use of this new class is guarded by a macro that enables three
levels of QStringView support:
1. offer QStringView, overload some functions taking QString with
QStringView
2. like 1, but remove all overloads of functions taking QStringRef,
leaving only the function taking QStringView. Do this only where
QStringRef overloads tradionally existed.
3. like 2, but replace functions taking QString, too.
This is done in order to measure the impact of QStringView on code
size and execution speed, and to help guide the decision of which
level to choose for Qt 6.
This first patch adds QStringView with most of its planned
constructors, but not much more than iterators and isNull()/isEmpty().
Further patches will add support for QStringView to QStringBuilder,
add QStringView overloads of functions taking QString, and add the
complete API of const QString to QStringView.
[ChangeLog][QtCore][QStringView] New class, superseding const QString
and QStringRef as function parameters, accepting a wide variety of
UTF-16 string data sources, e.g. u"string", std::u16string{,_view},
and, on Windows, L"string", std::wstring{,_view} without converting to
QString first.

We need Q_ASSERT in (C++11) constexpr functions, and the only way to
inject them in C++11 is to use the comma operator. E.g. in
QLatin1String:
constexpr QLatin1Char at(int i) const
{ return assert(1 >= 0), assert(i < size()), m_data[i]; }
The main problem with our existing Q_ASSERT is that while it is a
ternary expression in active mode, it was a statement in passive
mode. This is easily fixed by dropping the do-while loop and leaving
just its parenthesized exit condition. Add a cast to void, too,
ensuring that Q_ASSERT has type void in both passive and active modes.
But even in C++14 constexpr functions, which accept several
statements, Q_ASSERT needs to have a path through its conditionals
that is constexpr, but neither qt_assert(_x) nor qt_noop() are
constexpr. Nor can they be in C++11 (no void returns in C++11
constexpr functions). I fixed this by replacing qt_noop() with
static_cast<void>(0). The void cast is required so both 2nd and 3rd
arguments to the ternary are void (mixing void and non-void branches
in the ternary is only allowed if the void leg is a
throw-expression[1]).
As a drive-by, adjust to style guide, remove overparenthesization and
reverse the conditional in the ternary.
Apply it to QLatin1String where we had the problem that constexpr
functions had a narrow constract.
[1] should probably be extended to any [[noreturn]] void function,
e.g. std::terminate().
[ChangeLog][QtCore][QtGlobal] Q_ASSERT() and Q_ASSERT_X() now always
expand to expressions of type void that are usable in constexpr
contexts. This makes them usable in both C++11 and C++14 constexpr
functions.
