Construct a call site entry DIE describing a call within Scope to a callee described by CalleeSP and CalleeF.

IsTail specifies whether the call is a tail call. PCAddr points to the PC value after the call instruction. CallAddr points to the PC value at the call instruction (or is null). CallReg is a register location for an indirect call. For direct calls the CallReg is set to 0.
