Include anytostring inside concatstrings

This show another 10-12% improvement.

But not sure wether I'm missing something as to why it was done like this in the first place.

Ok, so as expected it's quite more complicated than that.

The issue is that objtostring works as follow:

• Check for various fast paths, and if we match return the optimized result
• Otherwise behave like a regular to_s call.

But nothing guarantees that to_s returned a string, so then anytostring is executed, and if what objtostring produced wasn't a string, it fallbacks to the any_to_s helper.

We can't do that in concatstrings because at that point we lost track of the object on which to_s was called.

So if we had to inline, it would be anytostring inside objtostring.

Have you thought more about putting anytostring inside objtostring?

Nope, perhaps something I should resume.
