This change enables emitting CFI unwind information for debugging purpose for targets with MCAsmInfo::ExceptionsType == ExceptionHandling::None. Currently generating CFI unwind information is entangled with supporting the exceptions, even when AsmPrinter explicitly recognizes that the unwind tables are being generated as debug information. In fact, the unwind information is not generated even if we specify --force-dwarf-frame-section, unless exceptions are enabled. The LIT test llvm/test/CodeGen/AMDGPU/debug_frame.ll demonstrates this behavior. Enable this option for AMDGPU to prepare for future patches which add complete CFI support.
