[PATCH] D37055: [ARM] Reverse PostRASched subtarget feature logic

Hi Matthias,

The reason for the inverse logic is because the decision isn't just based upon the CPU, but also the current mode. For the old CPUs, the post-RA scheduler should be used when compiling a function in arm mode, but not when in thumb mode because they only support Thumb1. I wanted to predicate on the Thumb2 capability, but then I would of still needed something else for cyclone and swift.

Thanks for the review,
sam
