Merge r230255,231245,231280,231986:
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.
--
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.
--
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.
--
Under duress, move check for target support of __builtin_setjmp/
__builtin_longjmp to Sema as requested by John McCall.
