Merge #10498: Use static_cast instead of C-style casts for non-fundamental types

9ad6746ccd Use static_cast instead of C-style casts for non-fundamental types (practicalswift)

Pull request description:

  A C-style cast is equivalent to try casting in the following order:

  1. `const_cast(...)`
  2. `static_cast(...)`
  3. `const_cast(static_cast(...))`
  4. `reinterpret_cast(...)`
  5. `const_cast(reinterpret_cast(...))`

  By using `static_cast<T>(...)` explicitly we avoid the possibility of an unintentional and dangerous `reinterpret_cast`. Furthermore `static_cast<T>(...)` allows for easier grepping of casts.

  For a more thorough discussion, see ["ES.49: If you must use a cast, use a named cast"](https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#es49-if-you-must-use-a-cast-use-a-named-cast) in the C++ Core Guidelines (Stroustrup & Sutter).
