Changes to the WebAssembly Target
---------------------------------
The WebAssembly target is no longer "experimental"! It's now built by default,
rather than needing to be enabled with LLVM_EXPERIMENTAL_TARGETS_TO_BUILD.
The object file format and core C ABI are now considered stable. That said,
the object file format has an ABI versioning capability, and one anticipated
use for it will be to add support for returning small structs as multiple
return values, once the underlying WebAssembly platform itself supports it.
Changes to the OCaml bindings
