Hi, Sergey,

thanks for the patch! LGTM with a minor comment below.

I propose to add a small test description to a comment:

SciMark is a popular benchmark, MC is a Monte Carlo Integration.

Sergey

This patch adds the aforementioned test with the use of the benchmark
framework introduced before. The default arguments are adjusted
according to the amount of cycles in the <scimark-2010-12-20.lua> file.
The arguments to the script can be provided in the command line run.

Checks are omitted since they were not present in the original suite,
plus the precise result value depends on the input parameter.
