Program Instrumentation: Sanitizers
-----------------------------------

    $ ./configure CXXFLAGS='-O0 -ggdb -fsanitize=address -fsanitize=undefined'

This compiles the nvptx-tools proper (but not libiberty) with the specified
sanitizers enabled.

If the 'run' test cases fail due to:

    nvptx-run: cuInit failed: out of memory (CUDA_ERROR_OUT_OF_MEMORY, 2)

..., per <https://github.com/google/sanitizers/issues/629>
"asan: problem calling NVIDIA CUDA libraries" run with
'ASAN_OPTIONS=protect_shadow_gap=false', to override the 'true' default;
<https://github.com/google/sanitizers/wiki/AddressSanitizerFlags#run-time-flags>.
