Turn Function.prototype.bind into a hydrogen stub optimized for the common case

This speeds up .bind by >10x as measured by
function f(a,b,c) {}

for (var i = 0; i < 10000000; i++) {
  f.bind(1); // or more arguments.
}

(Uses hydrogen-stubs rather than TF due to var-args + possible runtime fallback, which is still unsupported in TF.)
