There's currently no switch for this. However, you can use a a command
like this to see all installed packages that pull in your installed ghc:
emerge -pv --depclean dev-lang/ghc
I've filed a feature request bug for the switch that you have requested:

an obvious thing to optimize. This method already uses memoization, but
the cache is entirely discarded each time that a package is added to the
graph. I will see about making it salvage as much cache as possible when
a package is added.

I wasn't aware of that, so thanks for the tip.
