// This file defines the CallSite class, which is a handy wrapper for code that
// wants to treat Call and Invoke instructions in a generic way. When in non-
// mutation context (e.g. an analysis) ImmutableCallSite should be used.
// Finally, when some degree of customization is necessary between these two
// extremes, CallSiteBase<> can be supplied with fine-tuned parameters.
//
// NOTE: These classes are supposed to have "value semantics". So they should be
// passed by value, not by reference; they should not be "new"ed or "delete"d.
// They are efficiently copyable, assignable and constructable, with cost
// equivalent to copying a pointer (notice that they have only a single data
// member). The internal representation carries a flag which indicates which of
// the two variants is enclosed. This allows for cheaper checks when various
// accessors of CallSite are employed.
