The test is invalid, but worked until I changed <new> to stop
including <exception>.

This patch fixes it, pushed to master as obvious.

commit ce90d203cea33a4bfd4e415f601fe4486ecbb45d
Author: Jonathan Wakely <jwakely@redhat.com>
Date:   Wed Sep 2 18:37:17 2020

    testsuite: Add missing <exception> header to testcase
    
    This test no longer compiles because <new> stopped including
    <exception>, so std::set_terminate is not defined.
    
    gcc/testsuite/ChangeLog:
    
            * g++.old-deja/g++.abi/cxa_vec.C: Include <exception> for
            std::set_terminate.
