[PATCH] D44695: [clang-format] Partially revert r322749, replacing array with DenseSet

> One way in which DenseSet is better is that it supports StringRefs - we don't have to define hash. Seems like the lack of this override in core LLVM suggests that unordered_set is not commonly used with StringRefs.

Makes sense, thanks.
