test interprocess concurrency (#258)

* added cfoa_interprocess_concurrency_tests

* avoided C++14 digit separators

* stopped using exit codes to pass numerical info to parent

* Reorder includes to make msvc-14.0 happy

* made cumulative_stats interprocess concurrency safe

* disabled interprocess_concurrency_tests for Clang 3.5-8
(Boost.Process compile error)

* made test names shorter for the benefit of MINGW32
