re PR tree-optimization/69615 (0 to limit signed range checks don't always use unsigned compare)
PR tree-optimization/69615
* tree-ssa-reassoc.c (optimize_range_tests_var_bound): If rhs2 is lhs
of a cast from a same precision integral SSA_NAME in a bb dominated
by first_bb, retry with rhs2 set to the rhs1 of the cast. Don't emit
cast to utype if rhs2 has already a compatible type.
* gcc.dg/tree-ssa/pr69615.c: New test.
