Since Qt 5.3.0 we recommend that Linux distributions place a
SSE2-enabled copy of QtCore in a $PREFIX/lib/sse2 subdirectory (see Qt
5.3.0 changelog for details). Same for other hardware capabilities like
AVX2 and AVX512.
This use case was broken with the introduction of the 'relocatable'
feature, because the prefix is determined from the location of
libQt5Core.so and the relative path from libdir to prefix, which is
baked in at configure time.
We now try to locate the libdir below the prefix, and if that fails try
again in the upper directories.

When our ELF entry point function is started by the kernel, the stack is
aligned at 16 bytes. However, the stack is expected to be off by 8, due
to a preceding CALL instruction which didn't exist. This cauases a crash
further down as the compiler may generate aligned stack access.

Some AMD CPUs (e.g. AMD A4-6250J and AMD Ryzen 3000-series) have a
failing random generation instruction, which always returns
0xffffffff, even when generation was "successful".
This code checks if hardware random generator generates four consecutive
equal numbers. If it does, then we probably have a failing one and
should disable it completely.

One of our compilers for emscripten coerces all signaling NaNs to
quiet ones, so won't do any actual signaling. Anyone relying on them
to do so shall be disappointed, so it's better that they know about it
at compile-time - or, at least, have the ability to find it out.
Put the signaling NaN producers (and remaining (test) code using them)
under the control of a feature that's disabled when numeric_limits
claims double has no signaling NaN. Assume the bootstrap library
doesn't need signaling NaNs. Sadly, until C++20 <bit>, there's no
contexpr way to test that alleged signalling and quiet NaNs are
actually distinct.
Added some auto-tests for signaling NaN, including that it's distinct
from quiet NaN. Any platform on which the last fails should disable
this feature.

[ChangeLog][QtCore] Qt installations on the host system can now be
relocated, i.e. moved to other directories.
Add a new feature 'relocatable' that's by default enabled for
non-static builds
- on platforms where libdl is available,
- on macOS when configured with -framework,
- on Windows.
If the feature is enabled, the directory where plugins, translations
and other assets are loaded from is determined by the location of
libQt5Core.so and the lib dir (bin dir on Windows) relative to the
prefix.
For static builds, the feature 'relocatable' is off by default. It can
be turned on manually by passing -feature-relocatable to configure. In
that case, QLibraryInfo::location(QLibraryInfo::TranslationsPaths) and
friends will return paths rooted in the user application's directory.
The installed and relocated qmake determines properties like
QT_INSTALL_PREFIX and QT_HOST_PREFIX from the location of the qmake
executable and the host bin dir relative to the host prefix. This is
now always done, independent of the 'relocatable' feature.
Note that qmake is currently only relocatable within an environment
that has the same layout as the original build machine due to absolute
paths to the original prefix in .prl, .pc and .la files.
This will be addressed in a separate patch.

We can't use qt_scoped_lock/qt_unique_lock here, so port to

This is in preparation of deprecating QMutexLocker in favor
of std::unique_lock and std::scoped_lock.
In QFutureInterface, change the return type of mutex() from
QMutex* to QMutex&, so we don't need to deref when passing
to std::lock_guard. We need to keep the old method around
for BC reasons, so the new one needs an artificial function
argument for disambiguation. This will vanish come Qt 6.
