Upgrade to clap 3.

This requires moving away from the deprecated `clap_app!` macro. Clap's derive API (formerly `StructOpt`) is nicer anyway, because it's not stringly-typed. There is quite a bit of furniture moving in `execute.rs` to better separate the perf tools used for `bench_*` subcommands from those used for the profile subcommands.
