// * Each intrinsic is consistently exposed in JavaScript via 2 names:
//    * %#name, which is always a runtime call.
//    * %_#name, which can be inlined or just a runtime call, the compiler in
//      question decides.
//
// * IntrinsicTypes are Runtime::RUNTIME and Runtime::INLINE, respectively.
//
// * IDs are Runtime::k##name and Runtime::kInline##name, respectively.
//
// * All intrinsics have a C++ implementation Runtime_##name.
//
// * Each compiler has an explicit list of intrisics it supports, falling back
//   to a simple runtime call if necessary.
