The benchmark was making assumptions about number of
constructor/assignment operator calls, which are not valid in Qt 6,
after the implementation of QList has changed. Considering that we
already check number of constructions, copy constructions, etc., in
tst_qlist.cpp, remove the checks from the benchmark.

Open the file only if matching on content is needed.
Use QFileInfo::filePath() instead of QFileInfo::absoluteFilePath() in
QMimeDatabase::mimeTypeForFile(). filePath() does much less work, and so
is faster. Thiago Macieira helpfully explained in a review comment why
the absolute path is not useful for correctness here: "Nothing needs
absolute paths within the same application that would resolve the
relative path to absolute. You only need an absolute path if you're
communicating with another application that may be in a different
directory."
QMimeDatabase::mimeTypeForFile() checks fileInfo.isDir(), so the
fileName.endsWith(QLatin1Char('/')) check in
QMimeDatabasePrivate::mimeTypeForFileNameAndData() was redundant when
called from this function. The other two callers of that function now
check this condition before opening IO devices. This improves
performance of the two QMimeDatabase::mimeTypeForFileNameAndData()
overloads in the corner case.
Refactor and optimize QMimeDatabasePrivate::findByFileName() and its
usages. Previously each caller constructed a QFileInfo object and passed
QFileInfo::fileName() into this function. Now the callers simply pass an
absolute or relative path to a file into this function, which then uses
QFileSystemEntry::fileName() to exclude the path. Constructing QFileInfo
is relatively expensive, so this change slightly improves performance.
Optimize QMimeDatabasePrivate::loadProviders() by calling static
QFileInfo::exists() instead of constructing a QFileInfo object and
calling the non-static QFileInfo::exists() overload. Note that the
QFileInfo object was always created, even if QFileInfo::exists() under
an `if` and an `#if` was never called.
The following table contains the average results of the added benchmark
tst_QMimeDatabase::benchMimeTypeForFile() on my GNU/Linux system before

++i;
you're now supposed to write
volatile i;

int j = i; // volatile load
++j;
i = j; // volatile store
which matches more closely what hardware does.
Instead of fixing every use of volatile pre- or post-increment in this

Incidentally, the returned object has already been constructed as part
of advance()ing the iterator, so the new function is faster than
next() even if the result is ignored, because we're not calculating a
QString result the caller may not be interested in.
Use the new function around the code.

The sum of the first 100000 naturals is more than 2^32, so using an
int accumulator to collect the values is susceptible to overflow,
which is UB for signed integral types. So switch to an unsigned type.
We don't care about the actual sum, only having the various map
entries we fetch "used".
Since unsigned arithmetic is well-defined even when it overflows, we
can calculate the expected sum and verify it, to ensure that no matter
how clever the optimizer, it won't throw out the accumulator as
written but not read (and then optimize out all the tested code).
As a drive-by, rename one of the accumulators to match the rest.

test function since benchmarks get run repeatedly if they're quick.

(which was, of course, skipped if the test failed).
