At the moment, documentation of std::io::Write::write indicates that call to it ‘represents at most one attempt to write to any wrapped object’. It seems that such wording was put there to contrast it with pre-1.0 interface which attempted to write all the data (it has since been changed in [RFC 517]). However, the requirement puts unnecessary constraints and may complicate adaptors which perform non-trivial transformations on the data. For example, they may maintain an internal buffer which needs to be written out before the write method accepts more data. It might be natural to code the method such that it flushes the buffer and then grabs another chunk of user data. With the current wording in the documentation, the adaptor would be forced to return Ok(0). This commit softens the wording such that implementations can choose code structure which makes most sense for their particular use case. While at it, elaborate on the meaning of `Ok(0)` return pointing out that the write_all methods interprets it as an error. [RFC 517]: https://rust-lang.github.io/rfcs/0517-io-os-reform.html

It was already filtered out for emscripten, but wasi doesn't need dlmalloc either since it reuses `unix/alloc.rs`.

… r=lcnr Move WF/ConstEvaluatable goal to clause It can show up in a param-env, so I think it needs to be a clause kind. r? ```@lcnr``` or ```@oli-obk```
…lacrum std: only depend on dlmalloc for wasm*-unknown It was already filtered out for emscripten, but wasi doesn't need dlmalloc either since it reuses `unix/alloc.rs`.
bootstrap: check for dry run when copying env vars for msvc The new synthetic targets for mir-opt blessing aren't added to `builder.cc` during dry runs, causing `x.py test tests/mir-opt --bless` to crash on MSVC when it tries to copy env vars to the C compiler invocation. This PR adds a check for dry run to fix the panic.
…compiler-errors Make `Bound::predicates` use `Clause` Part of rust-lang#107250 `Bound::predicates` returns an iterator over `Binder<_, Clause>` instead of `Predicate`. I tried updating `explicit_predicates_of` as well, but it seems that it needs a lot more change than I thought. Will do it in a separate PR instead.
