    c++: assignment to temporary [PR59950]

    Given build_this of a TARGET_EXPR, cp_build_fold_indirect_ref returns t=
he
    TARGET_EXPR.  But that's the wrong value category for the result of the
    defaulted class assignment operator, which returns an lvalue, so we nee=
d to
    actually build the INDIRECT_REF.

            PR c++/59950

    gcc/cp/ChangeLog:

            * call.c (build_over_call): Use cp_build_indirect_ref.

    gcc/testsuite/ChangeLog:

            * g++.dg/init/assign2.C: New test.=
