[Bug c++/35368] [4.1/4.2/4.3/4.4 Regression] With #pragma visibility, `vtable for __cxxabiv1::__class_type_info' is emitted as a hidden-visibility relocation

We need to be careful about this.  We have a lot of ways to specify visibility:
dllimport/dllexport attributes, notshared attribute, visibility attributes on
classes.

I actually think the compiler is behaving as intended here.  To me:

  #pragma GCC push visibility(hidden)

is equivalent to applying:

  __attribute__((visibility("hidden"))) 

to all declarations in the scope of the #pragma.

And, a class with hidden visibility does have a hidden virtual table.

Why do we think this is a bug?
