  Log Message:
  -----------
  [XCOFF][AIX] Alternative path in EHStreamer for platforms do not have uleb128 support

Summary:
Not all system assembler supports `.uleb128 label2 - label1` form.
When the target do not support this form, we have to take
alternative manual calculation to get the offsets from them.
