This series provides the basic infrastructure for adding the new 32/64-bit
instructions in Power ISA 3.1 to target/ppc.

v5:
- Rebase on ppc-for-6.1;
- Change copyright line from new files;
- Remove argument set from PNOP;
- Add comments to explain helper_cfuged implementation;
- New REQUIRE_ALTIVEC macro;
- REQUIRE_ALTIVEC and REQUIRE_INSNS_FLAGS2 in trans_CFUGED;
- cmp/cmpi/cmpl/cmpli moved to decodetree.

v4:
- Rebase on ppc-for-6.1;
- Fold do_ldst_D and do_ldst_X;
- Add tcg_const_tl, used to share do_ldst_D and do_ldst_X code;
- Unfold prefixed and non-prefixed loads/stores/addi to let non-prefixed insns use the non-prefixed formats;
- PNOP invalid suffixes;
- setbc/setbcr/stnbc/setnbcr implemented;
- cfuged/vcfuged implemented;
- addpcis moved to decodetree.

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.

v2:
- Store current pc in ctx instead of insn_size
- Use separate decode files for 32- and 64-bit instructions
- Improvements to the exception/is_jmp logic
- Use translator_loop_temp_check()
- Moved logic to prevent translation from crossing page boundaries
- Additional instructions using decodetree: addis, pnop, loads/stores
- Added check for prefixed insn support in cpu flags

Well, I had applied them all, but I've now pulled patch 10 and onwards
out again, because it broke compile (there is no variable 'pc' in the
place that you use it).

Please make sure you do an (all targets) compile check at the *very
minimum* before posting in future.
