reland [js-perf-test] Adding micro benchmarks for for-in and keys patterns.

Browse Source 
In order to track certain critical code-patters we will start adding
micro-benchmarks that reflect common requests on http://jsperf.com.
In this first CL a number of property enumeration methods are added,
in the hope to get a clearer picture on future regressions.
