Gaps in Debugging features

[akharche]

Evaluate Debugging features supported by numba.cuda. We probably do not need a simulator feature as for us a dppy.kernel can be debugged by changing the dpctl.device_context to CPU. But the rest of the debugging functionality should be evaluated.

• Simulation

CUDA	DPPY
simulating CUDA_ENABLE_CUDASIM	no

• GDB support

CUDA	DPPY
@cuda.jit(debug=True)	only setting NUMBA_DPPY_DEBUG
filename info	filename info
line info	line info
no variable type information	no variable type information
cuda-memcheck	?

CUDA-MEMCHECK:

Make the same functionality @cuda.jit(debug=True): #174
