Improved ActiveSupport::Autoload performance. 

`ActiveSupport::Autoload#autoload` performance is improved in the default
case where a path is present. Since the full path name is not generated, it
isn't necessary to determine the full constant name either. This results in a
3x performance gain and reduces the number of Ruby objects generated. For a full
benchmark check [this gist](https://gist.github.com/2020228).
