This should be named to match the superclass method
(IsIncludedInAlternativeFieldTrial), per the comment above.

Actually, I can't use the word "Alternative" because the jni parser sees this as
"Alter" and "native" and strips the native. Also, if I rename the method in the
base class, I'll have to change a bunch of locations. Let's keep it as is for
this CL and we'll unify the names if the field trial proves useful to have for
more than a milestone or two.

Awesome feature. I'm sure that never causes problems.
