[PATCH][ARM] Add break in handling of comparisons in rtx costs function

[Kyrill Tkachov]

Hi all,

In arm_new_rtx_costs we need a break; statement after handling the comparisons 
cases. Otherwise we fall through and compute garbage. This small patch adds that.

Tested arm-none-eabi on qemu.

Ok for trunk?

Thanks,
Kyrill
