Uftrace timing profiler

UPBGE can be profiled using uftrace (https://github.com/namhyung/uftrace). But you need to compile with special gcc flags:

-finstrument-functions -finstrument-functions-exclude-file-list=xmmintrin,emmintrin

These flags allow instrumentation of the code and also disable instrumentation for SSE inline functions.

After this you can record your test case:

uftrace record blender file

and report/replay/graph the output.
