This series contains 4 new instructions for POWER9 ISA3.0
Use newer qemu load/store tcg helpers and optimize stxvw4x and lxvw4x.

    01:  darn: Deliver a random number
    02:  lxvw4x - improve implementation
    03:  stxv4x - improve implementation
    04:  lxvh8x:  Load VSX Vector Halfword*8
         stxvh8x:  Store VSX Vector Halfword*8
    05:  lxvb16x: Load VSX Vector Byte*16
         stxvb16x: Store VSX Vector Byte*16

* Fix lxvw4x/stxv4x translation as LE/BE were both similar 
  one in tcg and other as helper
* Rename bswap32x2 to deposit32x2 as it does not need to 
  swap content(32bit)
* stxvh8x had a bug as David suggested.

* More load/store cleanups in byte reverse routines
* ld64/st64 converted to newer macro and updated call sites
* Cleanup load with reservation and store conditional
* Return invalid random for darn instruction

* darn - read /dev/random to get the random number
* xxspltib - make is PPC64 only
* Consolidate load/store operations and use macros to generate qemu_st/ld
* Simplify load/store vsx endian manipulation
