We accept 'void *p; p->~void();' for MSVC compatibility since r148682. However, we were returning ExprError, rather than producing an AST, despite only diagnosing it with a warning. CodeGen noticed that the template function specialization had an invalid AST, and therefore didn't generate code for it. This change makes us produce an AST with a void pseudo-dtor call.
