[MCAsmInfo] Support UsesCFIForDebug for targets with no exception handling
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.

[AMDGPU] Test case demonstrating issues with generation of .debug_frame
This test case demonstrates that the Call Frame Information generation is
totally biased towards whether exceptions are enabled or not. Currently
LLVM does not generate CFI i.e. a .debug_frame for debug purpose even
if --force-dwarf-frame-section is enabled unless exceptions are enabled.
