Hi Richard,

I've put the implementation into config/arm/aarch-common.c, so
that it can be shared between the two targets. This required
a little bit of cleanup to the CC modes and constraints to get
the two targets to match up.
Changes for v2:
* Document overflow flags.
* Add "hs" and "lo" as aliases of "cs" and "cc".
* Add unsigned cmp tests to asm-flag-6.c.
Richard Sandiford has given his ack for the aarch64 side.
I'm still looking for an ack for the arm side.
The arm parts look good to me, there's not too much arm-specific stuff
that's not shared with aarch64 thankfully.
Thanks,
Kyrill
