When calling a builtin via a function pointer, torque tries to find any
builtin with the same parameter types for a descriptor. If no such
builtin exist, we currently crash.

Example:

type DoesNotExistFn = builtin(Context, Smi, Smi, Smi) => Smi;
macro TestMacro(c: Context, fn: DoesNotExistFn) {
  let result: Smi = fn(c, 1, 2, 3);
}
