> Implemented a instrumentation-based call graph profiler for Harmony.  The callgraph data structure are created and stored in EM component. 
> The patch is attached and three other additional source files are also included:
>     1. CallGraphProfileCollector.cpp, and CallGraphProfileCollector.h, to be added into directory \working_vm\vm\em\src
>     2. CallGphProfiler.cpp, to be added into directory: \working_vm\vm\jitrino\src\dynopt
> Another configuration file, server.emconf,  is also included.  You can add or remove "callgph_instrument" to enable and disable call graph in SD1_OPT and SD2_OPT compilations.  
> The call graph is only workable in server mode. Example command line is:
>       java.exe -Xem:server -Xmx512m -Xms512m -jar SPECjvm2008.jar scimark.fft.small
