bd709faba88565367b6d337466e6456481b5f3e8 by Matt Calabrese <calabrese@google.com>:
Implement `std::experimental::is_detected` in type_traits internals and move `is_detected_convertible` from variant's internals to type_traits internals. This is in preparation of creating workarounds for broken standard traits.

Speed up the absl::Seconds() function for floating-point values, roughly by 4.5x, since
we can take advantage of the fact that we're just taking a floating-point number and
splitting it into its integral and fractional parts.
