Fixes#95.
CPU-only mode is enabled by setting the `is_cpu_only` property while
defining a benchmark, e.g. `NVBENCH_BENCH(foo).set_is_cpu_only(true)`.
An optional `nvbench::exec_tag::no_gpu` hint can also be passed to
`state.exec` to avoid instantiating GPU benchmarking backends. Note that
a CUDA compiler and CUDA runtime are always required, even if all benchmarks
in a translation unit are CPU-only.
Similarly, a new `nvbench::exec_tag::gpu` hint can be used to avoid
compiling CPU-only backends for GPU benchmarks.
* Set `CUDA_MODULE_LOADING=EAGER` before `main`.
Fixes#136
* Portability for `setenv`.
* Remove pre-main CUDART usage and setup env in main.
* Fail examples if they deadlock.
This is the best way we have to diagnose a regression for
NVIDIA/nvbench#136.
* Add an initialize method to benchmark_manager for CUDA-related setup.
Benchmarks are created statically, so their constructors cannot call the CUDA APIs without breaking the CUDA_MODULE_LOAD setup.
This method is called from `main` after the environment has been configured.
