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. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@4778 c046a42c-6fe2-441c-8c8c-71466251a162
