Antony Polukhin d0e086ae4f Minor std::to_chars optimisation for base 10 ... __to_chars_10_impl is quite fast. According to the IACA the main loop takes only 6.0 cycles, the whole function with one iteration takes 10.0 cycles. Replacing the __first[pos] and __first[pos - 1] with __first[0] and __first[1] drops the function time to 7.53 cycles. 2019-09-09 Antony Polukhin <antoshkka@gmail.com> * include/bits/charconv.h (__detail::__to_chars_10_impl): Replace final offsets with constants.
