[Bug c++/14167] Unneeded C++ types are output in debug info due to use of static constants

Oops, not so clear after all.

Debug information for Class1 is no longer emitted, but debug information for
Class1::var1 is still emitted.  It just doesn't trigger the output of the
containing class any more.

If I add a real use of var1:

class Class1 {
public:
  static const int var1 = 1;
  static const int var2 = var1;
};

class Class2 {
  static const int var1 = 1;
  static const int var2 = 1;
};

int main(void)
{
  return Class1::var1;
}

Still no change.  We get a declaration for var1, but no definition for it, and
not even a declaration of the containing class.  It looks like this:

 <1><244>: Abbrev Number: 5 (DW_TAG_variable)
     DW_AT_name        : var1
     DW_AT_decl_file   : 1
     DW_AT_decl_line   : 3
     DW_AT_MIPS_linkage_name: _ZN6Class14var1E
     DW_AT_type        : <219>
     DW_AT_external    : 1
     DW_AT_declaration : 1
     DW_AT_const_value : 1

That's pretty useless.  It doesn't let a debugger print Class1::var1.
