    tree-optimization/112495 - alias versioning and address spaces

    We are not correctly handling differing address spaces in dependence
    analysis runtime alias check generation so refuse to do that.

            PR tree-optimization/112495
            * tree-data-ref.cc (runtime_alias_check_p): Reject checks
            between different address spaces.

            * gcc.target/i386/pr112495.c: New testcase.
