Changes for v3:
* Relax v8 simm13 checking for Tcc.
* Split gen_op_addx_int and reorganize to not clobber current cc_op.
* Do not replicate decoding for insns that can set cc_op.
Changes for v2:
* Fixes for JMPL, RETT, SAVE and RESTORE.
* Fixes for FMOV etc, which had lost gen_op_clear_ieee_excp_and_FTT.
* Allow conditional exceptions to be raised out of line
Use this for gen_check_align and conditional trap.
* Keep properties and feature bits in sync.

Hi Richard,
I've given v3 a run through my entire set of boot tests, and all the 32-bit SPARC
tests now pass. Running through the 64-vit SPARC tests I've found a couple of failures:
[1] ./qemu-system-sparc64 -m 256 -hda netbsd615.qcow2 -snapshot -nographic
(NetBSD)
-> Displays error on boot
[1] Illegal instruction (core dumped) chown root:opera...
