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.
- Update llvm tests and add clang test.
