4a40e23194 Special-case some paths inside tcg_out_tlb_read
a. Use 32bit arithmetics in TARGET_LONG_BITS == 32 case
b. Optimize byte access case in TARGET_LONG_BITS == 64 case

301f6d903a Fix the opcode value of LWA
That should teach one to not blindly trust documentation that will
(out of the blue) use decimal and binary representation for numbers in
the same chart for no apparent reason and without any prefixes, sigh..

Unbreaks MIPS.

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.

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)
