    [testsuite] require sqrt_insn effective target where needed
    
    Some tests fail on ppc and ppc64 when testing a compiler [with options
    for] for a CPU [emulator] that doesn't support the sqrt insn.
    
    The gcc.dg/cdce3.c is one in which the expected shrink-wrap
    optimization only takes place when the target CPU supports a sqrt
    insn.
    
    The gcc.target/powerpc/pr46728-1[0-4].c tests use -mpowerpc-gpopt and
    call sqrt(), which involves the sqrt insn that the target CPU under
    test may not support.
    
    Require a sqrt_insn effective target for all the affected tests.
    
    
    for  gcc/testsuite/ChangeLog
    
            * gcc.dg/cdce3.c: Require sqrt_insn effective target.
            * gcc.target/powerpc/pr46728-10.c: Likewise.  Drop darwin
            explicit skipping.
            * gcc.target/powerpc/pr46728-11.c: Likewise.  Likewise.
            * gcc.target/powerpc/pr46728-13.c: Likewise.  Likewise.
            * gcc.target/powerpc/pr46728-14.c: Likewise.  Likewise.
