Detailed benchmark outputs for functions
This patch adds an option to get detailed benchmark output for
functions.  Invoking the benchmark with 'make DETAILED=1 bench' causes
each benchmark program to store a mean execution time for each input
it works on.  This is useful to give a more comprehensive picture of
performance of functions compared to just the single mean figure.
