If program with initial contents doesn't link, try again as separable

Browse Source 
* We can't just link ALL programs as separable to be safe, since this
  hits the same problem of some shaders not being valid as separable :(.
* This should fix the case where a separable program with initial state
  was failing to link before, without breaking non-separable programs.
