New branch in GDC

[Iain Buclaw via D.gnu]

A new branch in GDC has been created.

https://github.com/D-Programming-GDC/GDC/tree/gdc-4.9

The master branch shall continue on being closely working with 
upstream development in GCC. So unless you enjoy being on 
bleeding edge, this is the branch you'd want to checkout when 
building gdc.

Expecting the auto-tester to break.  How far have you gotten with 
recognising our handy GCC version hints?
