Fix map modification in transition tree traversal.
...
While traversing the transition tree we build a work-list using the map
field of maps. Setting those map values with a write barrier causes
black-to-gray changes on maps which are currently not recognized as
such, hence their computed size might be off.

Support for precise stepping in functions compiled before debugging was started (step 2)
...
This change will ensure that full code with debug break slots is compiled and activated for all functions which already have activation frames.
This additional handling is only for functions which have activations on the stack, and that activation is of the full code compiled without debug break slots. In that case the full code is recompiled with debug break slots. It is ensured that the full code is compiled generating the exact same instructions - except for the additional debug break slots - as before. The return address on the stack is then patched to continue execution in the new code.
Also fixed SortedListBSearch to actually use the passed comparision function.
