This adds
- The parsing of `trivially_relocatable_if_eligible`,
`replaceable_if_eligible` keywords
- `__builtin_trivially_relocate`, implemented in terms of memmove. In
the future this should
- Add the appropriate start/end lifetime markers that llvm does not have
(`start_lifetime_as`)
- Add support for ptrauth when that's upstreamed
- the `__builtin_is_cpp_trivially_relocatable` and
`__builtin_is_replaceable` traits
