    enable sqrt insns for cdce3.c
    
    The test expects shrink-wrapping of the fsqrt call, but that will only
    occur when there is a usable sqrt insn.
    
    Arrange for dejagnu to add the options that enable the sqrt insn, if
    one is available, and to skip the test otherwise.
    
    
    for  gcc/testsuite/ChangeLog
    
            * gcc.dg/cdce3.c: Add sqrt insn options.
