    cse: Fix up CSE const_anchor handling [PR108193]

    The following testcase ICEs on aarch64, because insert_const_anchor
    inserts invalid CONST_INT into the CSE tables - 0x80000000 for SImode.
    The second hunk of the patch fixes that, the first one is to avoid
    triggering undefined behavior at compile time during compute_const_anch=
ors
    computations - performing those additions and subtractions in
    HOST_WIDE_INT means it can overflow for certain constants.

            PR rtl-optimization/108193
            * cse.c (compute_const_anchors): Change n type to
            unsigned HOST_WIDE_INT, adjust comparison against it to avoid
            warnings.  Formatting fix.
            (insert_const_anchor): Use gen_int_mode instead of GEN_INT.

            * gfortran.dg/pr108193.f90: New test.
