    testsuite: narrow the sync-4.C Darwin xfail to the versions that still fail
    
    This test always failed on powerpc-darwin9, but not for x86.
    
    From darwin10, a new unwind library was introduced that also failed this
    test for x86.  It seems that, finally, that unwinder has been fixed and
    this test is now passing on modern Darwin.
    
    Adjust the xfail to only the cases we cannot amend.
    
    gcc/testsuite/ChangeLog:
    
            * g++.dg/ext/sync-4.C: Adjust XFAIL to reflect that this issue
            is now fixed on modern Darwin.
