Detailed Description
template<typename FunTy, typename InstructionTy, typename ValueTy, typename CallSiteTy>
class llvm::StatepointBase< FunTy, InstructionTy, ValueTy, CallSiteTy >
Analogous to CallSiteBase, this provides most of the actual functionality for Statepoint and ImmutableStatepoint.
It is templatized to allow easily specializing of const and non-const concrete subtypes. This is structured analogous to CallSite rather than the IntrinsicInst.h helpers since we need to support invokable statepoints.
