LLVM backend for 6502
49ab3a626a
Today a simple function that only catches exceptions and doesn't run destructor cleanups ends up containing a dead call to _Unwind_Resume (PR20300). We can't remove these dead resume instructions during normal optimization because inlining might introduce additional landingpads that do have cleanups to run. Instead we can do this during EH preparation, which is guaranteed to run after inlining. Fixes PR20300.
