Committed: Use ARC_{FIRST,LAST}_SIMD_VR_REG instead of decimal literals in arc_conditional_register_usage; fix reg_alloc_order for DMA config regs

[Joern Rennecke]

2013-09-06  Joern Rennecke  <joern.renne...@embecosm.com>

        * config/arc/arc.c (arc_conditional_register_usage):
        Use ARC_FIRST_SIMD_VR_REG / ARC_LAST_SIMD_VR_REG.
        Also set reg_alloc_order for DMA config regs.
