// * Each intrinsic is exposed in JavaScript via:
//    * %#name, which is always a runtime call.
//    * (optionally) %_#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.

// Entries have the form F(name, number of arguments, number of return values):
// A variable number of arguments is specified by a -1, additional restrictions
// are specified by inline comments. To declare only the runtime version (no
// inline), use the F macro below. To declare the runtime version and the inline
// version simultaneously, use the I macro below.
