objectiveC++: When throwing c++ exception of an objectiveC object, use objc_exception_throw to raise the exception. // rdar://12605907 llvm-svn: 172091

// RUN: %clang_cc1 -x objective-c++ -triple x86_64-apple-darwin10 -emit-llvm -fcxx-exceptions -fexceptions -fobjc-exceptions -o - %s | FileCheck %s
Support catching Objective C pointers in C++ under the non-fragile NeXT runtime. Diagnose attempts to do this under the GNU or fragile NeXT runtimes. llvm-svn: 109298

Throw the switch to convert clang to the new exception handling model! This model uses the 'landingpad' instruction, which is pinned to the top of the landing pad. (A landing pad is defined as the destination of the unwind branch of an invoke instruction.) All of the information needed to generate the correct exception handling metadata during code generation is encoded into the landingpad instruction. The new 'resume' instruction takes the place of the llvm.eh.resume intrinsic call. It's lowered in much the same way as the intrinsic is. llvm-svn: 140049
