[PATCH 05/10] minmax: simplify __clamp_once() by using is_const_false()

[Vincent Mailhol via B4 Relay]

From: Vincent Mailhol <mailhol.vinc...@wanadoo.fr>

In __clamp_once(),

  __builtin_choose_expr(__is_constexpr((lo) > (hi)), (lo) <= (hi), true)

is equivalent to:

  !is_const_false((lo) <= (hi))

Apply is_const_false() to simplify __clamp_once().
