Compile QML files ahead of time with qmlcachegen
qmlcachegen compiles bindings and functions to C++ as far as
QQmlJSAotCompiler can. It does respect "pragma Strict" and rejects the
file if it's violated. Furthermore, it sets up the logger to follow the
qt.qml.compiler.aot logging category. By default it's completely silent.
Compiling the examples with qmlcachegen exposes a bug in the type
resolver where it returns an invalid generic type. It should never do
that. Fix it by returning JSValue.
[ChangeLog][QtQml][Important Behavior Changes] QML bindings and
functions are now compiled to C++ by qmlcachegen, if possible. Use the
qt.qml.compiler.aot logging category to receive diagnostics about the
compilation.
