   I named it "maint print dwarf2-cfi" - is that OK?

As per Andrew's maint info frame/maint print frame post, "main info
dwarf2-cfi" would be more appropriate.

   The attached version already resolves the data to verbose instructions 
   like DW_CFA_nop. Documentation is also there.

   Can I commit it?

Hmm, I'd prefer that all exported functions from dwarf-frame.c are
prefixed with dwarf2_frame_.

Could you sit on it for a while until I've finished moving over
dwarf-frame.c to mainline?
