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.
