Remove parameters from symbolized stack traces.

The expanded parameters take a lot horizontal space
and almost always push the file:line of the screen,
or text-wrap generating multiple lines per frame.

This CL tries to make the output less cluttered by
removing parameters from the unmangled method names.

It is possible to add the parameters back using
the --verbose command line argument.

Test: Add unit tests, investigate crashes from logcat
