[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.
