[Bug rtl-optimization/28108] New: Some cse optimizations require hash collisions

[amylaar at gcc dot gnu dot org]

cse.c:hash_rtx has the same problem as found before in cse.c:cselib_hash_rtx
(PR rtl-optimization/22445).  Hence, some optimiztions will only be done
if there is a convenient hash collision.

I.e. the MODE should not be used to calculate the hash value.
