Bug #16764: Module.const_source_location does not work on autoloaded constants

----------------------------------------
As we found when trying out `const_source_location` on a Rails project, it breaks when used on autoloaded constants.

Example:

```
$ cat foo.rb
autoload :Bar, './bar'

Bar

puts Module.const_source_location("Bar")
```

Returns `foo.rb:3`, when it should return `bar.rb:1`.
