* Fix memory corruption with type trimmingSimon Hausmann2017-08-231-3/+3
| | | | | | | | | | | | | | | | | | When creating a composite type, we register the meta-type in the qml loader thread. However we would require linking of the compilation unit to the QML/engine thread before we would be able to also undo that registration in unlink(), because we require the engine member to be set. If that did not happen, i.e. a qml type was loaded and trimmed from the cache before it was ever linked, we would end up with a dangling pointer in m_compositeTypes. Let's handle the case of CompilationUnit referring to a QML composite type separately from it being a compilation unit resulting from a .js file or in a plain QJSEngine environment.

This structure is propagated into the temps until it reaches the next member expression that uses the temp. Similarly QObjectType is added as IR type, next to VarType. The resolution inside the SSA type interference pass also requires passing through the QQmlEngine from the upper caller levels, in order to resolve the property type to a potential QMetaObject property.
