[ARM] Handle t2ADDri in ARMAsmPrinter::EmitUnwindingInstruction. This fixes a bug in ARMAsmPrinter::EmitUnwindingInstruction where llvm_unreachable was reached because t2ADDri wasn't handled. Test case provided by Tim Northover. rdar://problem/23270609 http://reviews.llvm.org/D14518 llvm-svn: 252557

ARM: use r7 as the frame-pointer on all MachO targets. This is better for a few reasons: + It matches the other tooling for iOS. + It matches EABI in more cases (i.e. Thumb-mode, and in practice we don't use ARM mode). + It leads to infinitesimally smaller code (0.2%, yay!). rdar://25369506 llvm-svn: 266003
