This loop here was a lonesome instance of a CAS loop in which adding
_mm_pause() was simple, because the code didn't use the usual pattern
do {
construct new value
} while (!testAndSet)
we use everywhere else in Qt.
In search of an elegant pattern that would allow to apply
qYieldCpu()/_mm_pause() to those idiomatic CAS loops, too, I've
reached for a lambda to construct the new value. This should apply to
all (tight) CAS loops, and may form the basis of an API extension
whereby we take that lambda as a function argument to encapsulate the
CAS loop in an algorithm (a function).

The http test data hasn't always been stable but for some reason
it fails far more than usual.
Originally the domain was a non-existing one, because it would then work
on any machine (even if not in CI) and would finish() (with error)
after failing to look up the domain in DNS. However, some machines in CI,
for some reason, take too long to do this and end up failing the test.
So, we change the URL to point to the network server in CI. This should,
at the very least, finish quickly when running in CI.

The string-to-integer conversion functions (toInt() etc) now support
the 0b prefix for binary literals. That means that base = 0 will
recognize 0b to mean base = 2 and an explicit base = 2 argument will
make toInt() (etc) skip an optional 0b.
[ChangeLog][QtCore][Important Behavior Changes] Due to the
newly-introduced support for 0b (binary) prefixes in integer parsing,
some strings that were previously rejected as invalid now parse as
valid. E.g., Qt 6.3 with autodetected bases would have tried to parse
"0b1" as an octal value and fail, whereas 6.4 will parse it as the
binary literal and return 1.
