From 6e557155810505525ec976cf7b9421e5c8970b55 Mon Sep 17 00:00:00 2001

Subject: Add benchmark for QChar

The benchmark isn't exhaustive, but tests the functions
that are heavily used by QtDeclarative.

For performance reasons, QtDeclarative has its own
implementation of various QChar functions (in
qdeclarativeutils_p.h). But we want to make the actual
QChar functions as fast, so that QtDeclarative can also
use them.
