Make it possible to have only function trace mode without emitting call stack traces, and vice versa. For function trace-only mode switch the default to allow capturing success stacks, as that's the most typical assumption. For call stack mode still default to emitting erroring stacks only, by default. Allow to force it one way or the other with -Sn or -Sy/-S arguments. Signed-off-by: Andrii Nakryiko <andrii@kernel.org>
