70ce1338ee Change remaining use of Addr64 in the VEX API to Addr. The reduces 
the size of VexGuestExtent to 20 bytes on a 32-bit platform. 
Change prototypes of x86g_dirtyhelper_loadF80le and 
x86g_dirtyhelper_storeF80le to give the address in the parameter
list type Addr. Likewise for amd64g_dirtyhelper_loadF80le and
amd64g_dirtyhelper_storeF80le.
Update switchback.c - but not tested.

ef35bc1491 Remove the valgrind_support parameter from LibVEX_Init. It's unused 
and looks like an anachronism. VEX is also cleaner without valgrind things
creeping in.

1efe44baeb Changed naming convention from 'PPC32' to 'PPC' for all VEX code common to both PPC32 and PPC64. 
And tidied up a fair bit while i was at it.

c036d8fee8 Fix switchback.c to reflect changes to call of LibVEX_Translate() 
Fix test_ppc_jm1.c to reflect direct linking
 - main -> __main etc
 - vex_printf -> vexxx_printf etc

e4b0a05930 Switchbacker updates 
- no longer using home-grown linker - simply compiling and linking switchback.c with test_xxx.c
 - updated to handle ppc64 (along with it's weirdo function descriptors...)
 - have to be careful not to use exported functions from libvex_arch_linux.a, hence vex_printf -> vexxx_printf in test_xxx.c

6481bde2da guest-ppc32 
~~~~~~~~~~
- store-with-update instrs: Valgrind pagefault handler expects faulting address >= current stack ptr, so we need to update the stack ptr register _before_ storing the old stack ptr
- branch_ctr_ok (bad calc for 'branch if %ctr zero' case)
- mcrf: scanning bitfields in the wrong direction
- on spotting the magic sequence, delta += 24
- updated DIPs for +ve-only args

host-ppc32
~~~~~~~~~
- fixed CMov reg usage
- fixed Pin_Call in emit_PPC32Instr(): we already know how far we're jumping
- fixed Pin_Goto in emit_PPC32Instr(): vassert right range of jump deltas

other-ppc32
~~~~~~~~~~
- exported OFFSET_ppc32_(various) for valgrind

c8e95f2908 Cleaned up front end a fair bit. 
Consolidated spr (non-gpr/fpr) register interface
Brought together separate guest XER flags to single word
 + fixed up switchback (latter slighly broken since r1002)
Few more comments, vasserts etc.
Updated page refs to PPC32 docs

10387d6109 Fix to run_translation: need to save LR on _caller's_ stack, and leave a hole for a callee to do the same on our stack.

ee3dba903c Added new instruction RdWrLR to read/write link register. 
The LR is saved in ISelEnv at the start of every bb
The LR is restored before any Goto.
This is needed because LR is a caller-saved register on PPC32, so helper functions may kill it.
(Could save/restore around each helper call, but not efficient)
