This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class. This results in this CL looking very big, but in terms of substance there is not much here. Differential revision: https://reviews.llvm.org/D24834 llvm-svn: 282188
