    Fix some comment nits
    
    While studying the TYPE_CANONICAL/TYPE_STRUCTURAL_EQUALITY_P stuff,
    I've noticed some nits in comments, the following patch fixes them.
    
    2024-04-16  Jakub Jelinek  <jakub@redhat.com>
    
            * tree.cc (array_type_nelts): Ensure 2 spaces after . in comment
            instead of just one.
            (build_variant_type_copy): Likewise.
            (tree_check_failed): Likewise.
            (build_atomic_base): Likewise.
            * ipa-free-lang-data.cc (fld_incomplete_type_of): Use an indefinite
            article rather than a.
