Subject: Introduce ImmutableCallSite, useful for contexts where no mutation is
 necessary. Inherits from new templated baseclass CallSiteBase<> which is
 highly customizable. Base CallSite on it too, in a configuration that allows
 full mutation. Adapt some call sites in analyses to employ ImmutableCallSite.
