compiler: Add a DebugHook expression

Browse source 
You can not create this expression manually, but there
is a pass in the compiler that adds it to all set
properties in a compilation run.

All it does is basically associate an id with an expression,
so that we can then in a later step have the interpreter do
something with that information. Apart from that, it tries to
be as transparent as possible.

The LLR lowering removes that expression again, just so we can
be sure it does not end up in the generated live code.
