Debugger: do not compile IC for accessors when debugging.

Debugger: do not compile IC for accessors when debugging.

The invariant is that as long as there is a debug info on
the shared function info, no accessor IC is compiled for
its code. That way we can guarantee that stepping into
accessors, which requires a debug info, works for accessors.

Michael, I thought about this and I think your idea with conditionally compiling
the IC is cleaner. So I implemented it. Please take a look!

Cool!
Okay, LGTM.
