Added CLEAN_JS and MINI_JS benches (#581)

* Added CLEAN_JS and MINI_JS benches

These benches are arbitrary code which is subject to change,
functionally the programs are identical.

* Forgot semicolon

* Adding parsing benchmarks for CleanJS & MiniJS

Added identical benchmark cases for parser.

* Migrating Clean and Mini benchmarks to new format

Adding js scripts in bench_scripts & moving exec, full and parser
benchmarks to new include_str!() macro.
