Add a -gmodules option to the driver and a -dwarf-ext-refs to cc1
to enable the use of external type references in the debug info
(a.k.a. module debugging).
The driver expands -gmodules to "-g -fmodule-format=obj -dwarf-ext-refs"
and passes that to cc1. All this does at the moment is set a flag
codegenopts.
