Could not fix git push/pull/rebase issues with https://github.com/llvm/llvm-project/pull/82264 so had to create this new pull request.  I've tried to address all the review comments from the previous PR:

Update computeDebugNamesUniqueHashes function to start with lowercase letter, to use a MutableArrayRef for the hashes parameter instead of SmallVector, and made uniqueHashCount a reference parameter, to allow the accelerator table class member to be properly updated. Also removed redundant namespace qualifier.
