[bytecode-generator] Move source code position for classes 

Move the source code position for classes to the point where the block
context has already been created. Previously, there would be a mismatch
between the context and the scope when using the ScopeIterator.

We paused at a point where, according to the source position, we already
are in a class scope, but according to the bytecode (context), we would
not yet have created the block context for the class.
