  Log Message:
  -----------
  [libc++] Fix constraints in `__countr_zero` and `__popcount`

Currently these two functions are constrained on `is_unsigned`, which is
more permissive than what is required by the standard for their public
counterparts. This fixes the constraints to match the public functions
by using `__libcpp_is_unsigned_integer` instead.
