Currently we emit `DW_AT_deleted` for `deleted` special-member
functions (i.e., ctors/dtors). However, in C++ one can mark any
member function as deleted. This patch expands the set of member
functions for which we emit `DW_AT_deleted`.

The DWARFv5 spec section 5.7.8 says:

  <non-normative>
  In C++, a member function may be declared as deleted. This prevents the compiler from
  generating a default implementation of a special member function such as a constructor
  or destructor, and can affect overload resolution when used on other member functions.
  </non-normative>
  
  If the member function entry has been declared as deleted, then that entry has a
  DW_AT_deleted attribute.

Thus this change is conforming.
