* Fix run-time string handling with regards to the new heapSimon Hausmann2014-11-211-1/+1
| | | | | | | | | | | | | | | | | Changed runtimeStrings to be an array of Heap::String pointers instead of indirect String pointers. Later that member along with other GC related members will go into a managed subclass. Meanwhile the generated code no more loads String pointers directly but just passes the index into the run-time strings to the run-time functions, which in turn will load the heap string into a scoped string. Also replaced the template<T> Value::operator=(T *m) with a non-template overload that takes a Managed *, in order to help the compiler choose the non-template operator=(Heap::Base *) overload. This allows removing a bunch of Value::fromHeapObject calls. Change-Id: I20415c0549d33cca6813441a2495976b66d4c00e Reviewed-by: Lars Knoll <lars.knoll@digia.com>

* Ported ExecutionEngine::newString and newIdentifier to Heap::StringSimon Hausmann2014-11-121-2/+3
| | | | | | | | | | Avoid the use of Returned<String> for newString and changed the identifier table to use Heap::String. This required moving some code back into Heap::String, but that's code that doesn't call back into the GC, so allocations and therefore future object moves aren't possible.
