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.

Previous code assummed 32 by 32 bit divmod operation, and survived
x86_64 test only by sheer luck. MIPS wasn't so forgiving.

* Fix typo in aliased div2
* "Optimize" aliased div2/divu2
* Fix two remaining branch retranslation problems
(Kudos to Andrzej Zaborowski)
* Rework goto_tb and set_jmp_target1
* Use correct size when flushing icache
* Use correct register selection for ORI
(Was harmless since in both cases srcreg was equal to dstreg)
