Fixed debug map in executable + DWARF in .o debugging on Mac OS X.

Added the ability to dump any file in the global module cache using any of
the "image dump" commands. This allows us to dump the .o files that are used
with DWARF + .o since they don't belong the the target list for the current
target.
