ABI: Fix for undefined "___cxa_deleted_virtual" symbol in MacOSX

Patch from Eddie Elizondo. Reviewed as D37830 (https://reviews.llvm.org/D37830).

On MacOSX the following program:

struct S { virtual void f() = delete; };
int main() { new S; }
Fails with the following error:

Undefined symbols for architecture x86_64:
  "___cxa_deleted_virtual"
This adds a fix to export the needed symbols.

Test:
