[PATCH] [ms-cxxabi] Elide dtor access checks for pass-by-val objects in callees

[Richard Smith]

  I think you should only be removing the direct access check of the parameter type, and not handling the base and member access checks -- they're effectively part of generating the destructor definition for the parameter's type, and aren't affected by which TU the check is performed in.

  If I understand correctly, these checks only occur as part of handling a function definition, which is not a SFINAE context, so I think this is not an issue.
