i965: Fix gl_FrontFacing emit on pre-gen6.
It's amazing this code worked. Basically, we would get lucky in register allocation and the tests using frontfacing would happen to allocate gl_FrontFacing storage and the instructions generating gl_FrontFacing but pointing at another register to the same hardware register. Noticed during register spilling debug, when suddenly they didn't get allocatd the same storage.
