re PR tree-optimization/59154 (internal compiler error: tree check: expected ssa_name, have integer_cst)
PR tree-optimization/59154
* tree-ssa-reassoc.c (maybe_optimize_range_tests): When changing
rhs1 of a cast and new_op is invariant, fold_convert it.
* tree-ssa-forwprop.c (ssa_forward_propagate_and_combine): Only call
simplify_conversion_from_bitmask if rhs1 is a SSA_NAME.
