 // List of functions with custom constant call IC stubs.

 // Installation of custom call generators for the selected builtins is
 // handled by the bootstrapper.
 //
 // Each entry has a name of a global function (lowercased), a name of
 // a builtin function on its instance prototype (the one the generator
 // is set for), and a name of a generator itself (used to build ids
 // and generator function names).
