DWARF may define a default lower-bound for arrays in languages defined
in a particular DWARF version. But the logic to suppress an
unnecessary lower-bound attribute was looking at the hard-coded
default DWARF version, not the version that had been requested.
Also updated the list with all languages defined in DWARF v5.
