[patch] Update DWARF codes for Fission

This patch to include/dwarf2.def updates the DW_FORM and DW_AT codes
for the Fission extensions. We've eliminated DW_FORM_GNU_ref_index,
and replaced DW_AT_GNU_ref_base with DW_AT_GNU_ranges_base. (The wiki
page at has been updated.)

OK for binutils and gcc?
