[PATCH v3 00/30] Base for adding PowerPC 64-bit instructions

[Richard Henderson]

Changes for v3:
  * More changes for decodetree.
  * Cleanup exception/is_jmp logic to the point exception is removed.
  * Fold in Luis' isa check for prefixed insn support.
  * Share trans_* between prefixed and non-prefixed instructions.
  * Use macros to minimize the trans_* boilerplate.
  * Fix decode mistake for STHX/STHXU.
