So, I think we should split -g/--call-graph into _two_, separate options:
--call-graph <variant>
-g
instead of turning the '<variant>' configurability off. Whatever is
configurable via .perfconfig ought to also have a command line
counterpart. This is pretty fundamental.
Ack on the .perfconfig aspect to choose a default for -g.
