re PR tree-optimization/85529 (wrong code at -O2 and -O3 on x86_64-linux-gnu)
PR tree-optimization/85529
* tree-ssa-reassoc.c (optimize_range_tests_var_bound): Add FIRST_BB
argument. Don't call get_nonzero_bits if opcode is ERROR_MARK_NODE,
rhs2 def stmt's bb is dominated by first_bb and it isn't an obvious
zero extension or masking of the MSB bit.
(optimize_range_tests): Add FIRST_BB argument, pass it through
to optimize_range_tests_var_bound.
(maybe_optimize_range_tests, reassociate_bb): Adjust
optimize_range_tests callers.
* gcc.c-torture/execute/pr85529-1.c: New test.
* gcc.c-torture/execute/pr85529-2.c: New test.
* gcc.dg/pr85529.c: New test.
