    c++: binding reference to comma expr [PR114561]

    We represent a reference binding where the referent type is more qualified
    by a ck_ref_bind around a ck_qual.  We performed the ck_qual and then tried
    to undo it with STRIP_NOPS, but that doesn't work if the conversion is
    buried in COMPOUND_EXPR.  So instead let's avoid performing that fake
    conversion in the first place.

    gcc/cp/ChangeLog:

            * call.cc (convert_like_internal): Avoid adding qualification
            conversion in direct reference binding.

    gcc/testsuite/ChangeLog:

            * g++.dg/conversion/ref10.C: New test.
            * g++.dg/conversion/ref11.C: New test.
