[Bug tree-optimization/23901] New: Dom jump-threading unrolls loops

["dje at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Dom jump-threading iteration can partially or completely unroll a loop.  This
prevents analysis of number of iterations and inhibits loop optimizations by
hiding the loop.
