Don't use QStringLiteral in comparisons

Browse Source 
For QLatin1String, operator== is overloaded, so comparing to a latin-1
(C) string literal is efficient, since strlen() is comparatively fast.

OTOH, QStringLiteral, when not using RVO, litters the code with
QString dtor calls, which are not inline. Worse, absent lambdas,
it even allocates memory.

So, just compare using QLatin1String instead.
