Bug 20198: quick_exit should not call destructors.
In C++11 18.5.12 says "Objects shall not be destroyed as a result of calling quick_exit." In C11 quick_exit is silent about thread object destruction. Therefore to make glibc C++ compliant we do not call any thread local destructors. A new regression test verifies the fix. I will note that C++11 18.5.3 makes it clear that C++ defines additional requirements for _Exit() to prevent it from executing destructors. Given that the point of _Exit() is to terminate the process immediately it makes sense the C and C++ should line up and avoid calling destructors. No failures. New regtest passes.
