gc_prefs: can be used to set custom GC settings during benchmarking (they will be reverted when the function returns)
no_compactions (default false): disables compactions during benchmarking, reverted when the function returns. Takes precedence over gc_prefs.
trials (default `Auto): runs this many trials for each sample. If `Auto, bench will automatically determine the number of trials to run based on how long it takes to run one trial. It will run enough trials n so that the mean cost of calling rdtscp is less than one percent of n, and it takes more than 0.01 seconds.
clock (default wall): controls time measurement method. Wall includes waiting on I/O
and when the process is suspended/descheduled; cpu only counts time spent on

run_time / input_size. "Stdev" reports the standard deviation for the "Run time" column. "Allocated" reports the average number of allocated words through the benchmarks.
"Warnings" may contain single characters indicating various things: 'm' indicates the minimum run time was less than 80% of the mean 'M' indicates the maximum run time was more than 120% of the mean 'c' indicates GC compactions occurred during testing 'a' indicates the number of words allocated was not the same in all tests
limit_with_to defaults to 72.
columns: select which columns to display.
`If_not_empty c means print the column
only if at least one cell contains something. It defaults to:
[`If_not_empty `Name; `Normalized_cycles; `If_not_empty `Warnings].
val bench :
(Test.t list -> unit) with_benchmark_flags
val bench_raw :
(Test.t list -> Result.t list)
bench_rawreturns a list documenting the runtimes rather than printing to stdout. These can be fed to print for results identical to calling bench.
