[PATCH] D50330: [RFC] Implement out-of-process allocator enumeration for macOS

[Dan Liew via Phabricator via llvm-commits]

delcypher added a comment.

- Implement SizeClassAllocator32 out-of-process enumeration
- Split implementation of out-of-process functions into their own header files. These can be included by the platforms that actually need this functionality.
- Remove `ProcessVMReaderContext::ReadErrorTy` and use `bool` instead.
- Move declaration of the ProcessHandle into `sanitizer_internal_defs.h`.
