Change code contains function to allow a return address just after the last instruction

Change code contains function to allow a return address just after the last instruction

Then patching the return sequence for debugger break at return a call is placed at the very end of the instruction stream causing the return address to be just after the actual instruction in the code object.

With this it will go to the 2.2 branch.

LGTM, but didn't we have an issue on ARM too?

The tests failing on ARM are due to the initial problem with the return address
being 0. I will fix that in a separate change.

LGTM.
