Both ARM and x86 can convert fp16 much faster in bulk than one at a

F16C isn't unconditionally available at compile time.
This code is implemented in C to ensure that there's no leakage of
inline symbols from the .obj file that was compiled by Visual Studio
with AVX support. Unfortunately, simd.prf uses $(CXX) instead of $(CC)
for all its sources, which means the file gets interpreted as C++ by
g++, clang++ and icpc. Those compilers at least don't leak any symbols.

BSD-3 licensed code from Google in a public header (hugh!).
The custom implementations for is_signed/is_unsigned are kept

The current implementation of qIsNull only returns true if the value is
positive zero. This behaviour is not useful for use cases like
QPointF::isNull, where QPointF(-0, -0).isNull() will return false.
There doesn't seem to be a reason why the function exhibits this
behaviour (-0.0 is not accounted for in the unit tests), and for the
case of QSizeF::scale it causes a bug: qIsNull is used to check for
division by 0.0 before it proceeds, which fails in the case of -0.0.

cast to an integer, which is required to allow passing non-local

The new return value is QMetaObject::Connection, it is a wrapper around

QObjectPrivate::Connection is now reference counted.
tst_qglobal.cpp:
This test set up an internal callback, and the callback do not set any
proper connection handle (and tbh, it would be hard for it to do so).
So the returned QMetaObject::Connection is invalid, and ok is false
