WIP Patch.
A patch I'm testing but I don't very much like this given it makes this rather
complex. The simple solution is to split the pattern into 2 for ARM and Thumb
state and mark the Thumb state one non-predicable. I don't want to split the
pattern into 2 if I can avoid it and would rather get it working correctly if
I can but anyway here goes.
Can you check and see if this helps in your case and if any other problems show
up ?
cheers
