    objsz: Don't call replace_uses_by on SSA_NAME_OCCURS_IN_ABNORMAL_PHI
[PR94423]

    The following testcase ICEs because the objsz pass calls replace_uses_by
    on SSA_NAME_OCCURS_IN_ABNORMAL_PHI SSA_NAME.  The following patch instead
    of that calls replace_call_with_value, which will turn it into
      xyz_123(ab) = 234;
