Various tests were setting the default locale and relying on cleanup()
to "restore" the C locale; which needn't actually be the locale we
started out in and, in any case, was the wrong locale for some tests.
So handle this via an RAII class that records the actual prior locale
and restores it on destruction.

Similar to commit cd64a96b31 we also need
to normalize the strings before comparison in order to be compliant with
the ECMAScript test suite.
This patch also adds the remaining test cases from
built-ins/String/prototype/localeCompare/15.5.4.9_CE.
Since the same tests are also failing with strcoll/qt_compare_strings,
this simplifies the code to always normalize except when using ICU
(which gets it right by default).

With ICU and on macOS it appears that the comparison is done on a
canonical form, while CompareString(Ex) does not do that, as the added
test verifies. Explicit normalization fixes that.
As a bonus, this also unifies the code path between regular Windows
and UWP by unconditionally using CompareStringEx (which requires
Vista or later).
This issue surfaced while running the ECMASCript 6 Conformance Test
Suite in QtQml.
This re-uses the existing test for localeAwareCompare, which was
disabled on Windows, macOS and Linux with ICU (the common case).

Make sure we properly handle both directional embeddings as well as
directional isolates to determine the direction of the string.
According to the latest version of the Unicode bidi algorithm,
parts of the string contained inside an directional isolate is
to be ignored when determining the paragraph direction. Embedding
markers themselves are to be ignored as well, but not the characters
inside an explicit directional embedding or override.
This is also some required pre-work to get our BiDi algorithm
updated to the latest version of the standard.

Since commit bf2160e72c, we can rely on
charNN_t support in all compilers except MSVC 2013, and since that
commit, we use (in 5.10, not 5.9, yet)
!defined(Q_OS_WIN) || defined(Q_COMPILER_UNICODE_STRINGS)
when we only need charNN_t, the type, as opposed to its library
support (u16string, char_traits<char16_t>, ...).
This patch splits the Q_C_UNICODE_STRINGS macro into two, adding
Q_STDLIB_UNICODE_STRINGS for when we need std::uNNstring, leaving
Q_C_UNICODE_STRINGS for when we need just charNN_t support.
In QDebug, when constructing a QChar out of a char16_t, cast to ushort
first, since QChar(char16_t) was only officially introduced in Qt 5.10.

Vectorized versions of ucstrncmp work on larger chunks of text
(typically 8 characters and an optional 4 more in some cases), so there
are now 4 extra sets of tests:
- strings of 1-65 characters, all different
- strings of 1-65 characters, all the same
- strings of 1-65 characters, all the same *except* the last character
- strings of 16 characters long, all the same except one, and that one
is different for every string (i.e. first string differs in first
char, second in second char, etc)
This should excercise both 1 or more iterations of the vectorized loop,
the detection logic inside the loop, and off-by-one cases.
The input is all ascii, so the ::compare() test will run them for both
QChar-QChar comparisson and for QChar-latin1 comparisson.

When replacing each copy of one text with a copy of another, we do so
in batches of 1024; if we get more than one batch, we need to keep a
copy of the sought text and replacement if they're part of the string
we're modifying, for use in later batches.
Also do the replacements in full batches of 1024, not 1023 (which left
the last entry in an array unused); marked some related tests as
(un)likely; and move some repeated code out into a pair of little
local functions to save duplcation.
Those new functions can also serve replace_helper(); and it can shed a
const_cast and some conditioning of free() by using them the same way
replace() now does. (There was also one place it still used the raw
after, rather than the replacement copy; which could have produced
errors if memcpy were to exercise its right to assume no overlap in
arrays. This error is what prompted me to notice all of the above.)
Added tests. The last error proved untestable as my memcpy is in fact
as fussy as memmove. The first two tests added were attempts to get a
failure out of it. The third did get a failure, but also tripped over
the problem in replace() itself. Added to an existing test function
and renamed it to generally cover extra tests for replace.
