Description
As discussed in https://github.com/uber/h3/pull/975, we would like the ability to run -fsanitize=memory -fno-sanitize-recover=memory on ARM, which we think is unblocked by upgrading clang.
Note: This might also affect the version of clang-format that the project uses, which is currently at 14.
@isaacbrodsky, let me know if I'm missing anything or got something wrong!

Research direction
Start with the discussion in pull request 975, then locate the project's clang and clang-format version configuration. Confirm what upgrading clang changes for clang-format 14 and whether the ARM memory-sanitizer command can run successfully; the work is done when ARM MSan is supported without breaking formatting or existing builds.
