add bind and noop functions

[nikoskalogridis]

Since those are handy generic use functions and I use them in @most/test package that I am going to submit soon I think its the right place to put them

If there are concrete use cases in mostjs libs for noop, I'm fine with adding it. Are there?

I think to add bind, we'd need to see perf test results for the performance of Function.prototype.bind across current VMs.
