Thanks for the PR! In principle, I think this makes sense. The majority of our hex printing is via `Twine::utohexstr`, which is always lower-case. I think the missing lower case argument in the calls to `llvm::utohexstr` are likely just oversights and should be updated.

There are several other places in this file that use `llvm::utohexstr`, some of which don't use the lower-case argument. Please could you update them all (and any tests that fail as a result of course). I note that in some cases (e.g. e_version), it's unlikely to matter due to the range of values that could be printed, but it's better to be consistent.
