  Log Message:
  -----------
  [libc++] Mark __u64toa and __u32toa as noexcept

The two functions don't throw, and the generated code is better when
we explicitly tell the compiler that the functions are noexcept. This
isn't an ABI break because the signatures of the functions stay the
same with or without noexcept.
