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)

f9ef6c2060 sigh; on amd64 do not place common symbols high in the address space
