Guillaume Chatelet fa404ae43a [libc] Enhance ArrayRef + unittests
This patch mostly adds unittests for `ArrayRef` and `MutableArrayRef`, additionnaly:
 - We mimic the behavior of `std::vector` and disallow CV qualified type (`ArrayRef<const X>` is not allowed).
   This is to make sure that the type traits are always valid (e.g. `value_type`, `pointer`, ...).
 - In the previous implementation `ArrayRef` would define `value_type` as `const T` but this is not correct, it should be `T` for both `MutableArrayRef` and `ArrayRef`.
 - We add the `equals` method to ease testing,
 - We define the constructor taking an `Array` outside of the base implementation to ensure we match `const Array<T>&` and not `Array<const T>&` in the case of `ArrayRef`.

Siva Chandra Reddy dbb131d53a [libc] Add a standalone flavor of an equivalent of std::string_view.
This class is to serve as a replacement for llvm::StringRef as part of
the plans to limit dependency on other parts of LLVM. One use of
llvm::StringRef in MPFRWrapper has been replaced with the new class.
