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

[Ben Hamilton via Phabricator via cfe-commits]

I'm fine with whichever approach we use, but I'll defer to @krasimir here.

(I'm not fully sure why `llvm::DenseSet` is better than `std::unsorted_set`, but I'm sure you and @krasimir understand the subtleties better than I do.)
