  Log Message:
  -----------
  [clang] Add -fdebug-default-version for specifying the default DWARF version

This flag decouples specifying the DWARF version from enabling/disabling
DWARF in general (or the gN level - gmlt/limited/standalone, etc) while
still allowing existing -gdwarf-N flags to override this default.
