a35e86c55f 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.

398ce98e4f Fix div[u]2. 
Previous code assummed 32 by 32 bit divmod operation, and survived
x86_64 test only by sheer luck. MIPS wasn't so forgiving.

0a878c4760 PPC TCG Fixes 
* 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)

e936243aca A branch insn must not overwrite the branch target before relocation. 
When a branch to label is translated it generates a reloc that is filled in
when the label is translated.  However, when handling an exception and
searching for the pc we abort the translation early and we sometimes
translate the branch but not the corresponding label and so no relocation
is done.  When the block is executed again the branch points to no-where.

It seems tcg/sparc/ is going to suffer from the same issue.
