- Removed hasABIFP, use DisableFramePointerElim instead.
- Removed special cases for iOS and WatchOS, the "no-frame-pointer-elim" attribute should be set by the frontend instead.
- R7 is now the frame pointer for Darwin, rather than MachO, and split stacks are enabled iff the frame pointer is r7.
- Fix up a lot of tests affected by the iOS/WatchOS change. Most of these were just a case of adding the "no-frame-pointer-elim" attribute, but there were a few cases testing the codegen differences with/without frame pointers, which needed changing.
- Rolled https://reviews.llvm.org/D23517 into this patch, as that was the original behaviour on iOS/WatchOS, and it wouldn't be possible to replicate the original iOS behaviour without https://reviews.llvm.org/D23517.
