Array destructuring assignments require a call to iterator.return if
the iterator hasn't been exhausted during destructuring.

Added an IteratorNext instruction to fetch the next
iteration value (empty if the iterator is done).
This will also help to implement array destructuring without
requiring huge amounts of byte code.

This requires a bit more work than simply pushing a
new BlockContext for the lexically declared variables,
as eval() and the Function constructor operate on the
global scope (including the lexically declared names).
To fix this introduce Push/PopScriptContext instructions,
that create a BlockContext for the lexically declared
vars and pushes that one as a global script context that
eval and friends use.

Add support for ES6 generators. Those are currently
always executed in the interpreter (we never JIT them),
to simplify the initial implementation.
Most functionality, except for 'yield *' expressions
are supported. 'yield *' will have to wait until we
support for(... of ...)

And implement / expose them via:
22.1.3.4 - Array.prototype.entries()
22.1.3.13 - Array.prototype.keys()
22.1.3.29 - Array.prototype.values()
22.1.3.31 - Array.prototype[Symbol.iterator]
Most tests for Array iterators now pass.
At the same time, expose them on TypedArray's prototype:
- 22.2.3.15 %TypedArray%.prototype.keys
- 22.2.3.29 %TypedArray%.prototype.values
- 22.2.3.6 %TypedArray%.prototype.entries
- 22.2.3.31 %TypedArray%.prototype[Symbol.iterator]
For TypedArray, test coverage improves a tiny bit (3 passing tests), but the
vast majority fail as it seems like the object structure for TypedArray is
currently incomplete as far as ES6 expects.
It seems that ES6 expects the object structure to be:
* %TypedArray% (inherits FunctionObject)
(this is the TypedArray intrinsic object, and responsible for initializing
the TypedArray instances)
* All the TypedArray ctors (e.g. UInt8Array)
These inherit %TypedArray%, and make a super call to it to do their work
* %TypedArrayPrototype% (inherits Object)
(this is the initial prototype for %TypedArray%)
* All the ctors have their own separate instance of this
* The instances also make use it
So, for instance, a lot of the tests attempt to access the prototype like:
var proto = Object.getPrototypeOf(Int8Array)
var keys = proto.prototype.keys
As ES6 expects Int8Array.prototype to be %TypedArray% (22.2.5), this expands to:
Object.getPrototypeOf(%TypedArray%)
which it expects to be %TypedArrayPrototype%.
But since we have no intrinsic object, and the ctors inherit
FunctionObject, we instead return the wrong prototype into 'var proto'.

Implemented by storing a backpointer to the Heap object
in the identifier.
Since identifiers now point back to their originating
String or Symbol, we can now easily mark all identifiers
that are still in use and collect those that aren't.
Since Identifiers are 64bit also add support for holding an
array index in there. With that an identifier can describe
any kind of property that can be accessed in an object. This
helps speed up and simplify some code paths.
To make this possible, we need to register all
IdentifierHash instances with the identifier table, so that
we can properly mark those identifiers.

Do this by always using odd numbers for protoId's, and
putting those into the same place as the InternalClass
pointers. That makes it possible to quickly check whether
the lookup contains a pointer to a valid heap object.

Internal classes are now allocated and collected through
the GC. As they are important to the deletion of other
objects (because of the vtable pointer living inside the
internal class), they need to get destroyed after regular
objects have been sweeped. Achieve this by using a separate
block allocator for internal class objects.
Our lookups do often contain pointers to internal classes,
so those need to be marked as well, so we don't accidentally
collect them.

Given the following expression
var x = MySingleton.MyEnumValue
where MySingleton is a QML (composite) singleton and MyEnumValue comes
from a QML declared enum, we had code in place up to (and including)
5.10 to attempt to optimize that expression to a enum constant at
compile time. In 5.10 that optimization does not exist anymore. In <=
5.10 we would also skip the optimization under certain circumstances
(too many statementes, etc.). The fallback that is in place for handling
this at run-time tried to be smart by avoiding the
QQmlContextWrapper::get lookup and return straight a reference to the
singleton as QObject. That works for regular property lookups, but it
fails when trying to look up something like an enum, that isn't a
meta-object property.

From now on we prefer nullptr instead of 0 to clarify cases where
we are assigning or testing a pointer rather than a numeric zero.
Also, replaced cases where 0 was passed as Qt::KeyboardModifiers
with Qt::NoModifier (clang-tidy replaced them with nullptr, which
waas wrong, so it was just as well to make the tests more readable
rather than to revert those lines).

When the code generation capability is not set, the first call of
canAllocateExecutableMemory will cause a warning about suboptimal
performance. The qWarning code checks, which thread caused the message
and QThread::current sets QCoreApplicationPrivate;s theMainThread when
it is called for the first time on Windows.
If we call that function inside a static initializer, it will be called
before QCoreApplication is created and thus set the main thread to the
one that called the function. This will cause a warning about QApplication
not being created inside the main() thread, but more importantly,
delivering of events will not work in WinRT applications afterwards.

So far we often began with the empty class again when creating
new internal classes. This allowed for multiple paths through the
internal class hierarchy ending up at the same internal class object.
But to be able to efficiently garbage collect internal classes, we
need to have only one path to each instance of an internal class.

So far the InternalClass only did describe the state of the class
itself, but it wouldn't change if some of the underlying
objects in the prototype chain changed. This now fixes that and
introduces a unique ID that completely describes the state of
the object including all it's prototypes.
This opens up for optimizing lookups down to one branch and a
load, independent of the depth of the value inside the prototype
chain.
