<DD>Returns the possible target functions that this callsite could call.
These targets do not include functions defined in externs. If this
callsite could call an extern function, then hasExternTarget() will
return true.
getKnownTargets() is a best effort only: the collection may include
other functions that are not actual targets and (if hasUnknownTargets()
is true) may be missing actual targets.
This method should not be called on a Callsite from a CallGraph
that was constructed with <code>computeForwardGraph</code> <code>false</code>.
