re PR tree-optimization/81588 (Wrong code at -O2)
PR tree-optimization/81588
* tree-ssa-reassoc.c (optimize_range_tests_var_bound): If
ranges[i].in_p, invert comparison code ccode. For >/>=,
swap rhs1 and rhs2 and comparison code unconditionally,
for </<= don't do that. Don't swap rhs1/rhs2 again if
ranges[i].in_p, instead invert comparison code ccode if
opcode or oe->rank is BIT_IOR_EXPR.
* gcc.dg/tree-ssa/pr81588.c: New test.
* gcc.dg/pr81588.c: New test.
* gcc.c-torture/execute/pr81588.c: New test.
