ac43d58d3a trans: Optimize initialization using repeat expressions
This elides initialization for zero-sized arrays:
* for zero-sized elements we previously emitted an empty loop
* for arrays with a length of zero we previously emitted a loop with zero
  iterations

This emits llvm.memset() instead of a loop over each element when:
* all elements are zero integers
* elements are byte sized

d721c1f9e3 trans: Reorder basic blocks in slice_for_each
This is mainly for readability of the generated LLVM IR and subsequently
assembly. There is a slight positive performance impact, likely due to
I-cache effects.

2fc3aec431 Auto merge of #43485 - nrc:rls-env-fix, r=Mark-Simulacrum
Update RLS

This pulls in 79d659e569 It should fix #43453. It increases the timeout for test runs and forces builds in RLS tests to happen sequentially, this prevents interference between env vars passed to Cargo or rustc.

Constrain the layout of Blake2bCtx for proper SPARC compilation

On SPARC, optimization fuel ends up emitting incorrect load and store
instructions for the transmute() call in blake2b_compress().  If we
force Blake2bCtx to be repr(C), the problem disappears.

7fa104f041 Rollup merge of #43458 - RalfJung:verbose, r=nikomatsakis
Fix printing regions with -Z verbose

When dumping MIR with `-Z verbose`, it would print regions on types, but not in the code. It seems the Rvalue printing code tried to be smart and guessed when the `Display` for `Region` would not possibly print anything.

This PR makes it no longer be smart, and just always use the `Display` like all the other code (e.g. printing types) does.

add a note to Vec's Extend<&T> impl about its slice specialization

From the regular documentation view, it's not at all apparent that [this specialization](5669c9988f/src/liballoc/vec.rs (L1879-L1891)) exists for `slice::Iter`. This adds a documentation blurb to the Extend impl itself to note that this optimization exists.

b5b7266b78 Rollup merge of #42959 - SimonSapin:nonzero-checked, r=sfackler
Make the "main" constructors of NonZero/Shared/Unique return Option

Per discussion in https://github.com/rust-lang/rust/issues/27730#issuecomment-303939441.

This is a breaking change to unstable APIs.

The old behavior is still available under the name `new_unchecked`. Note that only that one can be `const fn`, since `if` is currently not allowed in constant contexts.

In the case of `NonZero` this requires adding a new `is_zero` method to the `Zeroable` trait. I mildly dislike this, but it’s not much worse than having a `Zeroable` trait in the first place. `Zeroable` and `NonZero` are both unstable, this can be reworked later.

90ac6408ba Switch to begin_panic again
In https://github.com/rust-lang/rust/pull/42938 we made the compiler
emit a call to begin_panic_new in order to pass column info to it. Now
with stage0 updated (https://github.com/rust-lang/rust/pull/43320),
we can safely change begin_panic and start emitting calls for it again.

c802fc7103 Modified error for loop mut borrow conflicts
Error message now makes clear that mutable borrow conflicts on a single
value in a loop body is caused by the borrow outlasting a single pass of
the loop.
Loop conflicts are detected by seeing when two borrow locations are the
same - which indicates the same code being run more than once.

7c46c6c59d Auto merge of #43248 - llogiq:num-try-from, r=nagisa
improve the TryFrom implementations

This removes the need for a 128 bit storage by making use of the fact that there can be either no over/underflow, either one or both, and each time the target type suffices to hold the limit for comparison. This also means that the implementation will work in targets without 128bit support (unless it's for 128bit types, of course).

The downside is that the code looks a bit more complex.
