    Avoid changing type in the type_hash_canon hash

    When building a type and type_hash_canon returns an existing type
    avoid changing it, in particular its TYPE_CANONICAL.

            PR middle-end/114931
            * tree.cc (build_array_type_1): Return early when type_hash_can=
on
            returned an older existing type.
            (build_function_type): Likewise.
            (build_method_type_directly): Likewise.
            (build_offset_type): Likewise.=
