llvm.eh.sjlj.setjmp was used as part of the SjLj exception handling style but is also used in clang to implement __builtin_setjmp. The ARM backend needs to output additional dispatch tables for the SjLj exception handling style, these tables however can't be emitted if llvm.eh.sjlj.setjmp is simply used for __builtin_setjmp and no actual landing pad blocks exist. To solve this issue a new llvm.eh.sjlj.setup_dispatch intrinsic is introduced which is used instead of llvm.eh.sjlj.setjmp in the SjLj exception handling lowering, so we can differentiate between the case where we actually need to setup a dispatch table and the case where we just need the __builtin_setjmp semantic.
