vc4: Re-add R4 to the "any" register class.
I screwed this up in fdad4d24024ab7bc9b6b9cb6288f8b76ccac0d89 which was supposed to be making this code more maintainable. What's amazing is multithreaded FS showed the wins it did despite this bug. shader-db results: total instructions in shared programs: 103535 -> 100548 (-2.89%) instructions in affected programs: 83794 -> 80807 (-3.56%)
