Auto merge of #2219 - saethlin:more-benchmarks, r=RalfJung
Add more bench-cargo-miri programs These example programs are derived from long-running (>15 minutes) tests in the test suites of highly-downloaded crates (if I have my way, that runtime will not be correct for long). They should serve as realistic but also somewhat pathological workloads for the interpreter. The unicode program stresses the code which looks for adjacent and equal stacks to merge them. The backtraces program has an uncommonly large working set of borrow tags per borrow stack. This also updates the .gitignore to ignore files commonly emitted in the course of using these benchmark programs. --- The benchmark programs are so-named to avoid confusingly duplicating the names of the crates they are benchmarking. Is that a good idea? I started doing this so that I could use `cargo add` but now I'm not entirely sold on the names.
