Subject: [PATCH][ARM] Define predicable attribute for arm_abssi2 and arm_neg_abssi2

Hi all,
This patch updates the arm_abssi2 and arm_neg_abssi2 patterns in the ARM
machine description.
We define the predicable attribute based on the alternative. When the
patterns were introduced it was not possible to do that.
Now the second alternative in each of the patterns that supports predication
is defined as predicable.

No regressions on arm-none-eabi with qemu.

Ok for trunk?

Thanks,
Kyrill
