Summary: This adds three Function methods to handle function entry counts: setEntryCount() and getEntryCount(). Entry counts are stored under the MD_prof metadata node with the name "function_entry_count". They are unsigned 64 bit values set by profilers (instrumentation and sample profiler changes coming up). Added documentation for new profile metadata and tests.
