This patch supports dwarf debugging info for XCOFF format in the assembly path. Object path will be handled in followup patches.

Since I can not get the assembly file been assembled, I verify the debug info by checking the assembly files.

I have done some testing on the AIX system, this patch works well for some cases at 32-bit XCOFF.
