Pinging this for stage1, otherwise I'll forget about it and it'll fall through
the cracks...

Hi all,
I noticed that we don't handle simple reg-to-reg arithmetic operations in the
arm rtx cost functions. We should be adding the cost of alu.arith to the costs
of the operands. This patch does that. Since we don't have any cost tables yet
that have a non-zero value for that field it shouldn't affect code-gen for any
current cores.
Bootstrapped and tested on arm-none-linux-gnueabihf.
Ok for next stage1?
Thanks,
