Improve error location reporting for invalid aliases in old VME

When an alias declaration is missing a location, report the error with the
location of the alias declaration, not the object declaration.  This matches
the code patch in the new compiler, which also reports it accurately.

we can simply use the QQmlType and its know metaObject directly to perform

Fix composite type registration in the new compiler

When setting a property of a composite type like this

    property MyType foo: MyType {}

and MyType.qml defines the new type, we test for assignability of MyType to the
property foo. This test happens before MyType is instantiated and it relies on
the meta-type in the CompiledData being set. Therefore this patch makes sure
that the meta-type and the list meta-type are set accordingly at type
compilation time, not instantiation time, similar to how it's done in the VME.

Compile imported scripts in the loader thread

This has the benefit of blocking the GUI thread less and speeding up type
creation in the GUI thread (for types that import js libraries).

This patch also brings one behavioral change: Due to the parsing at type
instantiation type, things like syntax errors for script imports would only
generate a run-time warning and the code in the QML file would just see
"undefined". Errors in the script now generate real errors at component
compilation time, meaning the errors come out earlier and as real errors.

This patch implements the separation for the VME only (to keep the size
of this patch small).

V4 IR: do type inference/propagation before optimization.

This gives slightly better results for inplace increment/decrement,
where the operand has to be converted to a number. When that operand is
known to be a number, this conversion can be removed. By doing the
optimizations after typing, these conversions will not only turn into
assignments, but they will be propagated through the IR. That saves
a copy/move, which, in turn, will lighten the work for the register
allocator and the instruction selection.

Fix Component.onCompleted emission and bindings for composite types

When instantiating the composite type with a sub QQmlObjectCreator,
make sure to link the componentAttached objects back into the parent
creator. Similarly we need to collect the bindings the sub-creator
created, as finalize() is only called on the top-level creator.
