Testing DMD bootstrapped with other and older compilers.

The reason for using Travis is that
1) it's really hard to modify the configuration of the 
auto-tester (example:
2) resources/machines at the auto-tester are limited and paid by 
Brad personally - Travis allows five jobs in parallel for free

I agree that these random failures are really annoying and 
actually there has been work to improve this. The latest effort 
are the dub registry mirrors which will be added by default to 
the upcoming dub 1.6, e.g.:

The maximum time limit issue could be solved by reducing the 
amount of permutations tested even further.
