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.

The PPC64 store quad instruction is updating the address register with the
effective address of the store.  The instruction should not update the
address register.  The issue is due to the two putIReg() calls at the end of 
the instruction.  The two putIReg() calls were removed to fix the bug.  

This issue was reported in bugzilla 339336.
