ARM: add support for WatchOS's compact unwind information. llvm-svn: 251573

ARMv7k: base ABI decision on v7k Arch rather than watchos OS. Various bits we want to use the new ABI actually compile with "-arch armv7k -miphoneos-version-min=9.0". Not ideal, but also not ridiculous given how slices work. llvm-svn: 258975

On Darwin ARM, set the UNWIND_RESUME libcall to _Unwind_SjLj_Resume. This is important for the correct lowering of unwind instructions (which doesn't matter at all) and llvm.eh.resume calls (which does). Take 2, now with more basic competence. llvm-svn: 132295

Move the personality function from LandingPadInst to Function The personality routine currently lives in the LandingPadInst. This isn't desirable because: - All LandingPadInsts in the same function must have the same personality routine. This means that each LandingPadInst beyond the first has an operand which produces no additional information. - There is ongoing work to introduce EH IR constructs other than LandingPadInst. Moving the personality routine off of any one particular Instruction and onto the parent function seems a lot better than have N different places a personality function can sneak onto an exceptional function.
