Reviewers: mvstanton,
Description:
Debugger: clear ICs on activating step-in to correctly flood accessor pairs.
If we compile handlers to call accessors, Debug::HandleStepIn won't get
called. Therefore we need to clear ICs each time. This has not been
necessary before because we used to patch ICs for breaking, and restored
them with cleared ICs. This is no longer the case. We do not use ICs
for breaking anymore, so they are not implicitly cleared any longer.
