[Patch ARM] Fix typo in *<arith_shift_insn>_shiftsi

[Ramana Radhakrishnan]

As per RichardS's comment on the checkin to change the patterns for 
<arith_shift_insn>_shiftsi here. 
https://gcc.gnu.org/ml/gcc-patches/2014-05/msg02534.html

I toyed with the idea of removing this check but on balance it's 
probably safe to have this to have the condition fail before the 
recognizer kicks in.

Bootstrapped and regression tested on armhf.

Applied to trunk.

         number.
