While objects are being constructed, we don't have a reference to them
on the JS stack yet. So the constructor needs to protect itself against
being collected by putting the this object onto the JS stack.
Added an environment switch MM_EXACT_GC to test exact garbage

Now that we store them per QML file, they live in the type cache and
can outlive the engine. Therefore the engine needs to free to unlink
any remaining units upon destruction. This needs to be done after the
"death" of the memory manager, which is likely to sweep away any
function objects that also hold a reference to the compilation units.

Like this we properly unwind the js stack in all cases, and

At the moment we collect a lot of compilation units (one per binding
expression!), which for long running QML accumulates and creates a horrible
performance when trying to retrieve back traces. There is work in progress
to reduces the number of units down to one per QML file, and then the
fixed sorted QVector might proof to be a more efficient data structure
for the lookups.
But until that code lands, this patch proposes to use a QMap instead for the
time being, that tracks all functions. This brings down the qtquickcontrols
auto-test run from 2.5 minutes to just under a minute on my machine.
