MS ABI: Emit an error during IRgen on C++ exception handling

Currently, users get error messages about RTTI descriptor mangling with
no useful source location.  This addresses that.

Another approach would be to disable C++ exceptions by default in the
driver when using the Microsoft C++ ABI.  However, this makes it
impossible to parse system headers that use exception handling
constructs.  By delaying the error to IRgen, we can figure out if we
actually need to emit code for this construct.  Additionally, users who
are only interested in building refactoring tools on Windows still get a
correct AST without having to add flags.  Finally, this is consistent
with what we do for SEH.

Simplify replacement map by avoiding duplicate values and ensuring the values it does contain are necessary.

Items were being redundantly added to the replacement map (both when the
declaration was created, and then again when its definition was
constructed) which caused extra handling to be required when walking the
map (as elements may've already been replaced due to prior entries). By
avoiding adding the duplicates, the checks in the replacement handling
can be replaced with assertions.

ObjC IVars aren't added when the type isn't emitted after the interface extension

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@208014 91177308-0d34-0410-b5e6-96231b3b80d8
Build debug info for ObjC interface types at the end of the translation unit to ensure all ivars are included.

This takes a different approach than the
completedType/requiresCompleteType work which relies on AST callbacks to
upgrade the type declaration to a definition. Instead, just defer
constructing the definition to the end of the translation unit.

This works because the definition is never needed by other debug info
(so far as I know), whereas the definition of a struct may be needed by
other debug info before the end of the translation unit (such as
emitting the definition of a member function which must refer to that
member function's declaration).

If we had a callback for whenever an IVar was added to an ObjC interface
we could use that, and remove the need for the ObjCInterfaceCache, which
might be nice. (also would need a callback for when it was more than
just a declaration so we could get properties, etc).

A side benefit is that we also don't need the CompletedTypeCache
anymore. Just rely on the declaration-ness of a type to decide whether
its definition is yet to be emitted.

There's still the PR19562 memory leak, but this should hopefully make
that a bit easier to approach.

PR19598: Ensure temporary metadata nodes used in debug info are destroyed.

CGDebugInfo and DIBuilder were lax in their handling of temporary
MDNodes. All temporary nodes need to be deleted, which means they need
to be RAUW'd with a permanent node. This was not happening.

To ensure this, leverage DIBuilder's new ability to create both
permanent and temporary declarations. Ensure all temporary declarations
are RAUW'd, even with itself. (DIDescriptor::RAUW handles the case where
it is replaced with itself and creates a new, duplicate permanent node
to replace itself with)

This means that all temporary declarations must be added to the
ReplacementMap even if they're never upgraded to definitions - so move
the point of insertion into the map to the point of creation of the
declarations.
