Checks for cases where the floating-point overloads of various absl::Duration factory functions are called when the more-efficient integer versions could be used instead.

This check will not suggest fixes for literals which contain fractional floating point values or non-literals. It will suggest removing superfluous casts.


// Original - Providing a floating-point literal.
absl::Duration d = absl::Seconds(10.0);

// Suggested - Use an integer instead.
absl::Duration d = absl::Seconds(10);

// Original - Explicitly casting to a floating-point type.
absl::Duration d = absl::Seconds(static_cast<double>(10));

// Suggested - Remove the explicit cast
absl::Duration d = absl::Seconds(10);
