[CodeGen] Add public function to emit C++ destructor call.

Authored by zoecarver on Jun 23 2020, 9:48 AM.



Adds CodeGen::emitCXXDestructorCall, a function that creates a CodeGenFunction using the arguments provided, then invokes CodeGenFunction::EmitCXXDestructorCall.

This will allow other frontends (Swift, for example) to easily emit calls to object destructors with correct ABI semantics and calling convetions.

This is needed for Swift C++ interop. Here's the corresponding Swift change:

Can we do a design more like what we did with constructors?

  • Remove emitCXXDestructorCall and add getCXXDestructorImplicitParam.

@rjmccall I updated this patch to introduce the function getCXXDestructorImplicitParam instead. This should be closer to D79942. It seems like there is never more than one implicit parameter so, I just have it return a single llvm::Value*.
