result is always of the specified mode.

are always passed to simplify_gen_relational. Simplify NOT of
comparison operator in any mode, not just BImode.

of simplify_relational_operation to use const_true_rtx, not
const1_rtx. Abort if it ever returns a non-constant result.
* cfgloopanal.c (count_strange_loop_iterations): Use the function
simplify_relational_operation, not simplify_gen_relational, if
we're only interested in constant comparisons and will ignore
non-constant results.
