ART profiler usage.

This is a change to add args to some of the profiler related
functions, including installd commands.

Also read properties and set command line options for the runtime
profiling parameters.

Changed calls to isDexOptNeeded() to isDexOptNeededInternal().  This
needs additional arguments passed for profiles.
