    add sqrt options and test for sqrt support in ppc tests
    
    Some powerpc tests that require the fsqrt insn to be enabled
    explicitly use the -mpowerpc-gpopt option.  This fails if the fsqrt
    opcode is not available on the target machine.
    
    Switch to dg-add-options sqrt_insn for compile tests, that adds the
    option for the feature (pending approval of another patch for the same
    PR), and to dg-require-effective-target sqrt_insn for execution tests.
