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.
Newer versions of fmt have a ton of issues building on CTK 11.1, and 11.8 is the next available container we have built for CI. We may still work with some earlier versions, but we do not test them.
We no longer have CI images available for clang < 14, so drop official support.
Locking clocks is currently only implemented for Volta+ devices.
Example usage:
my_bench -d [0,1,3] --persistence-mode 1 --lock-gpu-clocks base

- `enum_type_axis` simplifies using integral_constants with type axes.
- `examples/enums.cu` demonstrates various ways of implementing parameter
sweeps with enum types.
