This PR adds the simproc String.reduceToSingleton`, which is disabled by
default and turns `"c"` into `String.singleton 'c'`.
Recall that the simproc `reduceSingleton`, which does the reverse, is
part of the default `simp` set.
This PR sets up the new integrated test/bench suite. It then migrates
all benchmarks and some related tests to the new suite. There's also
some documentation and some linting.
For now, a lot of the old tests are left alone so this PR doesn't become
even larger than it already is. Eventually, all tests should be migrated
to the new suite though so there isn't a confusing mix of two systems.
