QTimeZonePrivate::dataForLocalTime()'s handling of times in a

Supply the missing factor of a thousand.

Before this change we inserted newline only if an option has a
description and ended up with an arbitrary long line with all options.
[ChangeLog][QtCore][QCommandLineParser] Fixed a bug that caused the help
output to show two options or more in the same line if the options didn't
have a description.

With g++ 8.2.0, I get warnings when a QVarLengthArray<QString> calls
remove() or prepend(), as some tests in tst_QVarLengthArray do, as
they call memmove() "writing to an object of type ‘class QString’ with
no trivial copy-assignment; use copy-assignment or copy-initialization
instead"; which may indeed be a good argument for not using
QVarLengthArray<QString>, but its own tests do.

The copy-assign operator tests against other.d being NULL but the
copy-constructor didn't. This can only matter if the value being
copied has been moved from, so we could probably replace with an
assertion in practice, but we should at least be consistent.
Amended test to check this case too; and verified new test crashes
without this fix.

208c71768 introduced a problem for our users, who build on Windows with
/Zc:wchar_t-, which makes wchar_t a typedef for the type 'unsigned short',
preventing them from switching to more recent versions of Qt. While MSDN
recommends against this option, we can add more #if-ery to avoid compiler's
bailing out on a constructor's redefinition.

It's unclear when the reference to Unicode 4.0 standard
got added - it certainly predates the qt 4 git repository.
Anyhow, nowadays we're using later versions, and it doesn't
make much sense to highlight one specific version here.
Instead, use the correct technical term - UTF-16 code unit.
Also I added a 'correspond _to_', which sounds more common
to me.

QTimeZonePrivate::isValid() just checks m_id is non-empty; so we have
to leave m_id clear if we don't get a valid time-zone back when we ask
the JNI for one. Unfortunately, JNI gives us a "valid" default zone
if it doesn't recognize the given name; so check the known names of
this zone (or of zones with its offset); if the given ianaId isn't one
of them, assume this is a bogus zone.

QString::sprintf(), like the C printf-family, always includes two
digits in any exponent it outputs. Up to 5.6, number() and arg()
taking a double did the same; but changes at 5.7 to enable opting out
of the leading zero this implies for a single-digit exponent
accidentally opted out of it in args() and number(). This commit
fixes number() and arg() to include QLocaleData::ZeroPadExponent in
the flags they pass down to the C locale's doubleToString(), restoring
the prior behavior, including consistency with sprintf().
[ChangeLog][QtCore][QString] Formatting of doubles with single-digit

If LANGUAGE specified only the language, without any script or
country, and matched the value we'd got from other environment
variables, we were throwing away their knowledge of script and
country, leading to falling back on the default script and country for
that language, which might be at odds with what other environment
variables had told us.
Changed to only use LANGUAGE if it contradicts (or extends) what we
would otherwise have used. Clarified some comments in the process.
[ChangeLog][QLocale][Unix] When using LANGUAGE would lose information
about script or country, without changing language, use the locale
implied by LC_ALL, LC_MESSAGES or LANG.

First of all, this removes the UB that used to try and calculate the
distance between the two strings. That's a valid technique in assembly,
but dangerous in C++ and totally unnecessary. The compiler is perfectly
able to generate loops with a single induction variable all on its own.
Second, this commit makes the main loop use 32-byte comparisons (16
characters at a time), which is a reasonable size for strings. We use
AVX2 if that's available, or an unrolled pair of 16-byte loads
otherwise. After the existing 16-byte comparison, this commit inserts an
8-byte (4-character) comparison and then reduces the final, unrolled
comparison to just 3 characters.

be marked constexpr if qPopulationCount is also.
On MSVC2017 64bit this is not a problem because it uses builtins function
