QString: optimize finding size=1 needles in QLatin1Strings
Use memchr() if the needle has size() one, and add a fast path in
findString(QLatin1String, QStringView) to circumvent the QVLA path. We
might want to extend this and use a simple C array for very short
needles and (cached?) Boyer-Moore for anything larger.
Pick-to: 6.3
