Hi.
This patch adds various dwarf4 elements, plus DW_AT_GNU_odr_signature,
to include/dwarf2.h.
Ok to check in?
[I have a gdb patch that's ready to go in to support "comdat types".
And this will also be needed for the gcc side, which is currently
on the dwarf4 branch.]

DW_FORM_flag_present, DW_FORM_sig8.
(enum dwarf_attribute): Add DW_AT_signature, DW_AT_GNU_odr_signature.
