address sanitizer coverage of parallelization code-paths
We have mostly parallelization-off ASAN build (no SIMD, no OpenMP, no GPU, with tMPI run with 2 ranks). We would benefit from better coverage of more major code-paths to avoid nasty bugs

After a some head-scratching over GPU detection failing with CUDA and OpenCL too in ASAN builds, it turns out that GPU runtimes conflict with asan (GPU driver mmap-ed address space overlapping with the sanitizer's reserved space called "shadow gap").
Conclusion: need to use the
BTW, also realized that use of uninitialiezd memory detection is part of MSAN not ASAN.
