When a failed dynamic_cast<T&> (which is an lvalue) results in a throw, it should use invoke when needed. The fixes the Boost.Statechrt failures that motivated PR7132, but there are a few side issues to tackle as well. llvm-svn: 103803

// CHECK: landingpad { i8*, i32 }
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

CodeGen: Mark the runtime function __dynamic_cast as readonly & nounwind. This allows the optimizer to CSE dynamic_casts. llvm-svn: 174289
