Summary:
Added support for the -gline-directives-only option + fixed logic of the
debug info for CUDA devices. If optimization level is O0, then options
--[no-]cuda-noopt-device-debug do not affect the debug info level. If
the optimization level is >O0, debug info options are used +
--no-cuda-noopt-device-debug is used or no --cuda-noopt-device-debug is
used, the optimization level for the device code is kept and the
emission of the debug directives is used.
If the opt level is > O0, debug info is requested +
--cuda-noopt-device-debug option is used, the optimization is disabled
for the device code + required debug info is emitted.

Summary:
Some targets support only default set of the debug options and do not
support additional debug options, like NVPTX target. Patch introduced
virtual function supportsDebugInfoOptions() that can be overloaded
by the toolchain, checks if the target supports some debug
options and emits warning when an unsupported debug option is
found.
