2020-03-25Rollup merge of #70366 - cuviper:option-fuse, r=dtolnayDylan DPC-255/+344
Implement Fuse with Option The former `done` flag was roughly similar to an `Option` tag, but left the possibity of misuse. By using a real `Option`, we can set `None` when the iterator is exhausted, removing any way to call it again. We also allow niche layout this way, so the `Fuse` may be smaller. The `FusedIterator` specialization does want to ignore the possibility of exhaustion though, so it uses `unsafe { intrinsics::unreachable() }` to optimize that branch away. The entire `Fuse` implementation is now isolated in its own module to contain that unsafety. r? @scottmcm

2020-03-25Rollup merge of #70226 - RalfJung:checked, r=oli-obkDylan DPC-280/+337
use checked casts and arithmetic in Miri engine This is unfortunately pretty annoying because we have to cast back and forth between `u64` and `usize` more often that should be necessary, and that cast is considered fallible. For example, should [this](https://doc.rust-lang.org/nightly/nightly-rustc/rustc/mir/interpret/value/enum.ConstValue.html) really be `usize`? Also, `LayoutDetails` uses `usize` for field indices, but in Miri we use `u64` to be able to also handle array indexing. Maybe methods like `mplace_field` should be suitably generalized to accept both `u64` and `usize`? r? @oli-obk Cc @eddyb

resolve: Remove `rustc_attrs` as a standalone feature gate Now it only gates specific built-in attributes. So if you want to make a rustc attribute, make it a built-in (this was already the case in practice for some time).
