ASAN enabled builds require more stack space and therefore our call
depth limits should be lower.
In my measurements with a recursion through arrow functions with the
interpreter, as per the test case in the bug report, different types of
builds require different amounts of stack space. On x86-64 Linux, I
measured, by printing $rsp and subtracting:
Debug: ~6k
Debug with -Og: ~590 bytes
Release with -O2: ~570 bytes
Release (-O2) with ASAN: ~40k

This way you can enable or disable the JIT when configuring Qt. The
conditions for the availability of the JIT have also been cleaned up.
There is no reason anymore to artificially restrict availability on x86
and x86_64. The reason for the existence of those clauses are old
problems on windows that have been fixed by now. However, on arm and
arm64, we need a specialization of the cacheFlush() function for each OS
to be supported. Therefore, restrict to the systems for which such a
specialization exists. iOS and tvOS are technically supported and you
can enable the JIT via the feature flag now. Due to Apple's policy we
disable it by default, though.

Also, evaluation of expressions is notoriously expensive and unreliable

Somehow, we ended up with two codepaths doing essentially the same
thing: constructing a JS value from a QVariant. metaTypeToJS is invoked
from QJSEngine::toScriptValue, whereas fromVariant() is used in various
places internally.
metaTypeToJS lacks proper handling for a number of cases, such as
builtin types like QPointF, which lead to toScriptValue(QPointF)
(incorrectly, and uselessly) constructing a VariantObject which couldn't
then do anything useful.
[ChangeLog][QtQml] QJSEngine::toScriptValue will now return correct
JavaScript objects in more cases, for example, for gadget types like
QPointF.
[ChangeLog][QtQml] QJSEngine::toScriptValue now uses the same
behavior as the rest of the engine when building JavaScript values, which
will cause the types of some returned JavaScript objects to change. For
instance, string lists are now returned as sequence objects, not array
objects, and QChar now constructs a JavaScript string.

When resolving names in the context of QML bindings, we now direct
runtime access to QQmlContextWrapper::resolveQmlPropertyLookupGetter. At the
moment this does basically the same as Runtime::method_loadName, which
we called earlier. However this now provides the opportunity to optimize
lookups in the QML context in a central place.
When performing a call on a scope or context object property, we also
did not use a CallName() instruction - which would have gotten the
thisObject wrong - but instead we use a dedicated
CallScopeObjectProperty and CallContextObjectProperty instruction. These
rely on identifying these properties at compile time, which goes away
with lookups (and also doesn't work when using ahead-of-time
compilation). Therefore the qml context property lookup is using a
getPropertyAndBase style signature and
Runtime::method_callQmlContextPropertyLookup uses that.
For the tests to pass, some error expectations need adjusting. In
particular the compile-time detection of write attempts to id objects is
now delayed to the run-time.
The old code path is still there and will be removed separately in the
next commit (as it is massive).
