    IBM Z: Preserve exceptions in autovec-*-signaling-eq.c tests
    
    DSE, DCE, and other passes are removing redundant signaling comparisons
    from these tests, but the whole point is to check that GCC knows how to
    emit them.  Use -fno-delete-dead-exceptions to prevent that.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/s390/zvector/autovec-double-signaling-eq.c:
            Preserve exceptions.
            * gcc.target/s390/zvector/autovec-float-signaling-eq.c:
            Likewise.
