Revision: 4778
          http://svn.sv.gnu.org/viewvc/?view=rev&root=qemu&revision=4778

Log Message:
-----------
Shuffle contents of tcg_target_reg_alloc_order

Move reserved/volatile registers down. Currently qemu_ld/stXX are
marked with TCG_OPF_CALL_CLOBBER and since memory accesses are
frequent and R3 through R12 are volatile moving this down results in
less spills and tighter generated code.
