re PR tree-optimization/54810 (VRP doesn't handle comparison of narrowing cast like comparison of BIT_AND_EXPR)
PR tree-optimization/54810
* tree-vrp.c (register_edge_assert_for_2): Handle
NAME = (unsigned) NAME2; if (NAME cmp CST) for
narrowing casts to unsigned integral type like
NAME = NAME2 & CST2; if (NAME cmp CST) where CST2
is the max value of the unsigned integral type.
* gcc.dg/tree-ssa/vrp85.c: New test.
