    testsuite: Fix tree-ssa/alias-access-path-13.c on 32bit platforms (PR
106216)

    For gcc.dg/tree-ssa/alias-access-path-13.c to work, SRA must think of
    accesses to foo.inn.val and to foo itself as different ones, i.e. they
    need to have different offset and size, which on 32bit platforms they
    do not.  Fixed by replacing a dummy long int field of the union with a
    struct of two integers.

    Tested by:
      make -k check-gcc RUNTESTFLAGS=3D"tree-ssa.exp=3Dalias-access-path-13=
.c" and
      make -k check-gcc RUNTESTFLAGS=3D"--target_board=3Dunix'{-m32}'
tree-ssa.exp=3Dalias-access-path-13.c"
    on an x86_64-linux, also with patched SRA to verify it still tests the
    original intent.
