Update micro benchmarks

Remove some micro benchmarks that provided no added value, rename others
to have shorter names and add a few; some Olden benchmarks and a couple
of benchmarks to exercise concurrency.

the total run time is collected (in CSV format) and then the minimum,
mean, maximum and standard deviation are calculated based on the collected
values.

building the benchmarks works, including dil, which is added as a
submodule for simplicity (and keeping track of working version).
