DWARF64 was implemented at version 3, so if a DWARF version less than 3 is specified, DWARF64 does not get selected. Since XCOFF64 requires DWARF64, the modified tests fail on 64-bit AIX. This patch bumps these tests to dwarf version 3 to maintain test coverage on 64-bit AIX.
The input ll will specify the DWARF info, see Dwarf Version.
So could we change the input "Dwarf Version" to 3 or above if the version is not a test point to the tests? Keeping these debug tests for AIX should be preferred.
