[NewPM] Port HWASan and Kernel HWASan Port hardware assisted address sanitizer to new PM following the same guidelines as msan and tsan. Changes: - Separate HWAddressSanitizer into a pass class and a sanitizer class. - Create new PM wrapper pass for the sanitizer class. - Use the getOrINsert pattern for some module level initialization declarations. - Also enable kernel-kwasan in new PM - Update llvm tests and add clang test.

// Test that HWASan and KHWASan runs with the new pass manager.
[HWAsan][NewPM] Handle hwasan like other sanitizers Move it as an EP callback (-O[123]) or in addSanitizersAtO0. This makes it not run in ThinLTO pre-link (like the other sanitizers), so don't check LTO runs in hwasan-new-pm.c. Changing its position also seems to change the generated IR. I think we just need to make sure the pass runs. Reviewed By: leonardchan Differential Revision: https://reviews.llvm.org/D88936
