The following plugs possible overflow issues in vn_reference_compute_hash
and possibly in vn_reference_eq. The inchash "integer" adds are a bit
of a mess, but I know overloads with different integer types can get
messy, so not this time. For hashing simply truncate to 64bits.
PR tree-optimization/90242
* tree-ssa-sccvn.cc (vn_reference_compute_hash): Use
poly_offset_int for offset accumulation. For hashing
truncate to 64 bits and also hash 64 bits.
(vn_reference_eq): Likewise.
