True

Actually I wanted to say that if we prevent `foo` from devirtualizing and have two call sites:

CS1: { foo, bar }
CS2: { bar, baz }

then CS2 will still be devirtulized, so specifying `-wholeprogramdevirt-skip=foo` is actually telling WPD that all call sites potentially calling `foo` should remain virtual.
