When a cached compilation unit depends on an import that is implemented as a
Qml C++ plugin and that plugin in turn loads an asynchronous component that is
cached, we would get a crash in the typeloader and a failing assertion
(ASSERT: "d->m_mainThreadWaiting == false" in file qml/ftw/qqmlthread.cpp, line 300)
This is because we did not implement the asynchronous loading within the loader
thread for cached compilation units. This is simply done using a posted event,
using the same mechanism used for other async load methods.

This is among other things needed to fix the qml import scanner to detect
dependencies from .js files correctly.
The patch also fixes the use of Q_QML_EXPORT towards Q_QML_PRIVATE_EXPORT
where appropriate and corrects the wrong include path for the double conversion
code to actually be relative to the file it is included from. This worked by
accident because of other include paths present in the build.

This removes the bulk of the code. A few smaller cleanups remain, to be
done in smaller changes as they move code around.
Additionally the "optimize" option of qqmlbundle was removed. It called QQmlScript::Parser::preparseData,
which however was not implemented and always returned an empty QByteArray. Therefore "optimize" would not

We need to generate the property caches before we can try converting the
signal handler expressions in the AST to function declarations, as that
conversion requires looking up the signal signature / meta-data from the
property cache. This in turn requires rewriting the property cache
generator code to operate on the data structure we have before creating
the QV4::CompiledData.

Commit 0aadcf8077840068eb182269e9ed9c31ad12f45e that pre-compiles the
expressions in PropertyChanges {} introduced a regression in where the
evaluation context was incorrect and thus bindings would not be able to
access the correct properties. For example
PropertyChanges {
target: someObject
y: height / 2
}
Here height should be looked up in the context of "someObject", not of the
PropertyChanges element.
This patch introduces an auto-test that verifies that the lookup context is
correct and fixes the bug by disabling accelerated compile time property
lookups for binding expressions that are requested from a custom parser.

Propagate QObject properties in member expressions across temporaries
as part of the type interference SSA pass. This replaces the earlier
attempt to resolving QObject properties in fieldMemberExpression()
in the codegen, but it was incomplete and now things like the following
are fully resolved:
var tmp = blah.somePropertyThatReturnsAQQuickItem; <-- QQuickItem property return type propagated into tmp
var width = tmp.width; <-- and picked up here again to resolve the index of width instead of by name
With this patch Temp gets a helper structure with a function pointer,
initialized to aid the resolution of properties in Qt meta objects. 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.

objects at QML compile time
This avoids having to do a string lookup for ids and in the import cache at
run-time, before we can do a string hash lookup in the property cache. Instead
we resolve final properties in the context and scope object at compile time and
look them up at run-time using their index instead. The dependencies to these
properties are also tracked separately and recorded in the compiled data.
This is merely the initial patch. There's a lot left to do, such as having
specialized getter and setters for specific property types. Setters are missing
altogether right now and will fall back to name lookup.

Also adds necessary hooks to treat types as Singletons. Basic

seem to have problems.
In addition removes unnecessary toString() call in the equivalent

This is done by re-using the JS code generator from the new compiler. A few bugs were
fixed on the way:
* The index into the compiledData->runtimeFunctions array is not the same as the function
index when they are collected (from the AST), as for example binding expressions may create
extra V4IR::Function objects that break the 1:1 mapping. Therefore the JS code gen will return
a mapping from incoming function index to V4IR::Module::Function (and thus runtimeFunction)
* Binding expressions in the old backend get usually unpacked from their ExpressionStatement node.
The reference to that node is lost, and instead of trying to preserve it, we simply synthesize it
again. This won't be necessary anymore with the new compiler in the future.
* Commit 1c29d63d6045cf9d58cbc0f850de8fa50bf75d09 ensured to always look up locals by name, and so
we have to do the same when initializing the closures of nested functions inside binding expressions
(in qv4codegen.cpp)
* Had to change the Qml debugger service auto-test, which does toString() on a function that is now compiled.
Even if we implemented FunctionPrototype::toString() to do what v8 does by extracting the string from the
file, it wouldn't help in this test, because it feeds the input from a string instead of a file.
* In tst_parserstress we now end up compiling all JS code, which previously was only parsed. This triggers
some bugs in the SSA handling. Those tests are skipped and tracked in QTBUG-34047

This patch changes the exception handling API in the engine slightly, encapsulating
any use of direct throw statements and catch blocks with concrete types. In the future
we need to be able to change the way these are implemented, in order to ensure that
the correct stack unwinding code is triggered for throw and re-throw.
This patch separates the C++ exception object thrown from the V4 exception
(that includes value, throwing context pointer) and stores the latter inside
the engine.
In order for that to compile, ExecutionEngine::StackTrace and StackFrame had to
move into the QV4 namespace directly.
In addition the syntax for catching exceptions changes from
try {
...
} catch (QV4::Exception &ex) {
ex.accept(context);
QV4::ScopedValue exceptionValue(scope, ex.value());
}
to
try {
...
} catch (...) {
QV4::ScopedValue exception(scope, context->catchException());
}
Context::catchException() checks if there's a "current" exception in the engine,
and if not assumes that we caught an unrelated exception and consequently re-throws.
partiallyUnwind() is also gone and replaced with rethrowException(), in order to
encapsulate the re-throw.
Lastly, in the future nesting try/catch blocks isn't going to be possible due to
limitations in the common C++ ABI with regards to foreign exceptions.

We need this since it could happen that in QQmlComponentPrivate::loadUrl we did
QQmlTypeData *data = QQmlEnginePrivate::get(engine)->typeLoader.getType(url, loaderMode);
and got a sync QQmlTypeData even if we asked for async, and thus the async loader was never notified
when it finished and we were never loaded.
Situation in which this can happen is:
* ListView with an async Loader as delegate
* Loader loads two items A and B, while A is a B
* Item 0 of the ListView triggers an async loading of A that triggers the sync loading of B
* Item 1 of the ListView triggers an async loading of B
* Since B is already being loaded (though in sync), we just add ourselves to the people that want to be notified
* sync loading of B is done and QQmlDataBlob::tryDone does not call the callbacks because it's sync
* Item 1 is never finished loading
