R600: silence GCC warning 

GCC believes it may be possible to not return a value from the switch:
  lib/Target/R600/SIRegisterInfo.cpp:187:1: warning: control reaches end of non-void function [-Wreturn-type]

Add an unreachable label to indicate that this is not possible and still permit
switch coverage checking.
