  Log Message:
  -----------
  DebugInfo: Disable ctor homing for types with only deleted (non copy/move) ctors

Such a type is never going to have a ctor home, and may be used for type
punning or other ways of creating objects.

May be a more generally acceptable solution in some cases compared to
attributing with [[clang::standalone_debug]].
