[SystemZ] Update non-pic DWARF encodings
As pointed out by Rafael Espindola, we should match the DWARF encodings produced by GCC in both pic and non-pic modes. This was not the case for the non-pic case. This patch changes all DWARF encodings to DW_EH_PE_absptr for the non-pic case, just like GCC does. The test case is updated to check for both variants. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181222 91177308-0d34-0410-b5e6-96231b3b80d8
