  -----------
  [libcxx] Stop using builtin type traits for is_floating_point and is_arithmetic.

Based on an issue brought up in https://reviews.llvm.org/D67900, this commit reverts the changes to is_floating_point and  is_arithmetic made in D67900.

After D67900 landed, __float128 behaved differently in those two type traits, causing compiler errors in numeric limits (and possibly others).
