QML: When available, use QQmlAccessors to read properties.
When a property is read from a QObject or the QML scope object, and we
can statically resolve the type to qreal/QObject/int/bool/QString, and
the property has an accessor declared for it, then use that accessor to
do the read.
This collapses the path of e.g.:
Runtime::getQmlScopeObjectProperty
-> QObjectWrapper::getProperty
-> QObjectWrapper::getProperty
-> LoadProperty
-> QQmlAccessor::read
(all of which do various checks for all the stuff mentioned above) to:
Runtime::accessQmlScopeObjectQRealProperty
-> QQmlAccessor::read
which is a simple 4-line function, and doesn't need to do any check.
According to valgrind, this saves 170 instructions on x86 for the
simple binding:
Item {
width: height
}
