        PR tree-optimization/79673
        * tree-ssa-pre.c (compute_avail): Use wide_int_to_tree to
        convert the [TARGET_]MEM_REF offset INTEGER_CST, scrapping off
        irrelevant address-space qualifiers and avoiding a
        ADDR_SPACE_CONVERT_EXPR from fold_convert.

        * gcc.target/i386/pr79673.c: New testcase.
