DEAD-MACPTR referenced in saved currency-converter application

Description

It was reported in  http://clozure.com/pipermail/openmcl-devel/2008-July/008420.html that a saved CurrencyConverter application (presumably built from the trunk as of roughly the date of that message) references a DEAD-MACPTR during "early application initialization".

The current 1.2 version doesn't seem to be affected by this.

This seems to have been caused by code which runs after ObjC class info is cleared from the objc class maps causing (per-session) class addresses to be reentered in those maps just before the image is saved (leading to a situation where REVIVE-OBJC-CLASSES tried to enter classes in those maps and choked on the presence of DEAD-MACPTRs there.)

This should be fixed in r10255 and r10256. Since the issue's a little subtle, it might be wise to have REVIVE-OBJC-CLASSES clear the class maps before doing things (just in case something else repopulates them after they've been cleared.)
