Adjust the changes from r230255 to bail out if the backend can't lower __builtin_setjmp/__builtin_longjmp and don't fall back to the libc functions. llvm-svn: 231245

Fix test/CodeGen/builtins.c for platforms that don't lower sjlj Opt in Win64 to supporting sjlj lowering. We have the backend lowering, so I think this was just an oversight because WinX86_64TargetCodeGenInfo doesn't inherit from X86_64TargetCodeGenInfo. llvm-svn: 231280

Only lower __builtin_setjmp / __builtin_longjmp to llvm.eh.sjlj.setjmp / llvm.eh.sjlj.longjmp, if the backend is known to support them outside the Exception Handling context. The default handling in LLVM codegen doesn't work and will create incorrect code. The ARM backend on the other hand will assert if the intrinsics are used. llvm-svn: 230255
