This adds two flags:
-fno-cygprofile-exit Don't insert any calls for function exit.
-fno-cygprofile-args Don't pass any arguments to the cygprofile functions (the implementer has to figure out the caller address themselves)
These are useful for reducing the size and run-time overhead of the instrumentation.
