Before this patch we were parsing the attributes as section offsets, as that is what apple_names is doing. However, this is not correct as DWARF v5 specifies that this attribute should use the Reference form class. This also updates all the testcases (except the ones that deliberately pass a different form) to use the correct form class. llvm-svn: 328773
