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