If we are procedurally setting a shadowable property, the read register
for the value will be converted to var. We can therefore not just
retrieve the property type again in the code generator to determine what
we have to do.
What we actually need is the information on the original scope type of
the lookup. We need to know what exactly the base type was supposed to
be. To that effect, store the scope of the target for each conversion in
QQmlJSRegisterContent.
We need to circumvent the questionable optimization of "deduplicating"
functions that certain compilers exhibit, like we do for the getters.

The function prolog logic is now separated in its own basic block. The
first "real" block with user code starts at offset 0.
Having the function prolog as a hidden part of the first block caused
some inconsistencies in block generation and would create empty blocks.
This happened for example when a back edge of a loop would target offset
0 in code where a loop condition is the very first set of instructions
that are run. This is because the target block offset didn't exist due
to it being part of the hidden prolog block.
Validation for the basic blocks was also added. This checks for three
things at the moment:
1. That return and throw blocks don't have jump targets.
2. That the basic blocks graph is connected.
3. That jump targets are the first offset of a block.
Test tst_QmlCppCodegen::basicBlocksWithBackJump_infinite() is expected
to fail because it contains an infinite loop and the basic blocks that
are generated for it are inconsistent due to dead-code elimination
happening earlier in compilation.
Debug outputs for dumping basic blocks were also adapted to reflect
these changes.

If you pass the enumeration type to the Q_FLAG macro, you'll get an
qmltypes entry where the type is marked as a flag, but where aliasName
is empty. For backwards compatibility reasons, we cannot static_assert
that the type passed into QFlags is actually a flag type.
When using the interpreter, this does not cause any issues, because the
code there does not need to distinguish flags and enums.
When compilation is enabled, we do however generate bogus code, which
either leads to a wrong result, or to a crash if ASAN is enabled.
Avoid the issue by detecting that the enum is missing, and by rejecting
that case.

This gives us a unified interface to all kinds of QML types at run time
and reduces the effort of finding corresponding type attributes.
QQmlType is much larger than CompositeMetaTypeIds. Most composite types,
however, are initially referenced by URL, and we call typeForUrl anyway.
typeForUrl already creates a mostly functional QQmlType; we only need to
add the dynamic metatypes. The same type can be retrieved later and
associated with the actual CU using the compositeTypes hash. That way,
we don't need any extra type. We do, however, incur the cost of creating
the QMetaTypePrivate instances when first referencing a type. This could
be optimized, like many things in this area, by using thread safe lazy
initialization.
Now some QQmlTypes implicitly depend on the CUs they were created for.
This creates problems if the CUs are removed but the types still
persist. Such a situation can arise if you create and delete engines. In
order to avoid it, we:
1. Make the compositeTypes hold a strong reference to the CUs
2. When unlinking, avoid dropping the property caches (as those are used
to hold the metaobjects)
Now, however we got a cyclic reference between the CU and its
QQmlType(s). To resolve this, we clear the QQmlTypes on unlinking.
Finally, to avoid deletion recursion when clearing the last CUs on
destruction of the QQmlMetaTypeData, we move the compilation units out
of the way first.
All of this still doesn't work if multiple CUs hold the same QQmlType,
since compositeTypes can only hold one CU per type and that may be the
one that gets removed first. Therefore, we cannot allow such a situation
to happen and have to create a new QQmlType if it arises. It can only
arise if you have multiple engines loading the same QML components,
which should be fairly rare.
For inline components, we apply a similar trick: You can either find an
inline component by Url, and receive any type that matches, no matter
what CU it belongs to. Or you can request an inline component type that
belongs to a specific CU. It turns out we don't have to store the
containing type of an IC at all. Also, we slightly change the naming of
internal components' "class names" since we want to use the inline
components' element names for them.

By default, the QML engine does not enforce signatures given as type
annotations to functions. By passing different types than the function
declares, you can get different behavior between the interpreter/JIT and
the AOT-compiled code. In addition, in interpreted or JIT'ed mode, we
pass all non-primitive value types as references. This means, if you
modify them within the called function, the modifications are propagated
back to the place where the value was loaded from.
Enforcing the signature prevents all of this, at a run time cost. Since
we have to coerce all arguments to the desired types, the function call
overhead grows. This change introduces a pragma
"FunctionSignatureBehavior" which you can set to "Ignored" or "Enforced"
to choose one way or the other as universal way of handling type
annotations.

Treating the arguments as generic registers causes the basic blocks pass

Tracking the change signals is brittle and error prone. We have bindings

When detecting an ambiguous type, we need to invalidate the entry in the
list of types, rather than delete it. If we delete it and we get yet
another version of the type, we'll add that one just like it was not
ambiguous.
Furthermore, we cannot check the type name when looking for ambiguity.
The QML name can be bent and twisted in various ways, to import
ambiguous-looking types under different names, so that they are actually
not ambiguous.

The only place where revisions matter is at the boundary between
composite and non-composite types. The revision of the first composite
type inherited from determines which members of all composite ancestors
are available. Therefore, store the revision together with the base type
and pass it through the imports to have it available. Then use it to
check availability of methods and properties.
The test exposes two further problems, which are fixed, too:
1. If no method is found to call, we need to generate an error in the
type propagator. We don't know what the call will result in, after
all, and the code generator should reject it.
2. We need to check the right scopes for hasOwnMethod(). Otherwise we
might not find methods that are available.
