i965/reg: Make brw_sr0_reg take a subnr and return a vec1 reg

Browse Source 
The state register sr0 is really a collection of dwords not a SIMD8
anything.  It's much more convenient for brw_sr0_reg to return the
particular dword you're looking for rather than a giant blob you have to
massage into what you want.
