Address some QStringLiteral data duplication
Each use produces a new UTF-16 array that contains the string data. This duplicates the data as many times as you “call” QStringLiteral with the same argument. It does so even within a single translation unit. Common C string literals, on the other hand, are allowed to share a single memory location.
