stabilize const_int_pow

Browse source 
Also stabilize constctlz for const ctlz_nonzero.

The public methods stabilized const by this commit are:

  * `{i*,u*}::checked_pow`
  * `{i*,u*}::saturating_pow`
  * `{i*,u*}::wrapping_pow`
  * `{i*,u*}::overflowing_pow`
  * `{i*,u*}::pow`
  * `u*::next_power_of_two`
  * `u*::checked_next_power_of_two`
  * `u*::wrapping_next_power_of_two` (the method itself is still unstable)
