Massif, Cachegrind, Memcheck, Helgrind, Perf, OProfile, Callgraph,
Gcov, GProf are all contributing to this unified launch. In most
cases the extent of this contribution means they contribute to
an extension point we've defined in the profiling launch plugin
(schema/org.eclipse.linuxtools.profiling.launch.provider.exsd).

I think running all available tools would be too much. The best
option is to run some default tool, and allow the user to change
their preferences should they wish to use another tool. Keep in
mind that most users may not know what profiling tools are out
there so having an option like "Profile Memory", and using
Valgrind's Memcheck plugin by default would be a very sane thing
to do.
