rustbuild: Use src/rustc for assembled compilers

The `src/rustc` path is intended for assembling a compiler (e.g. the bare bones)
not actually compiling the whole compiler itself. This path was accidentally
getting hijacked to represent the whole compiler being compiled, so let's
redirect that elsewhere for that particular cargo project.

Closes #38039

annotate stricter lifetimes on LateLintPass methods to allow them to forward to a Visitor

this unblocks clippy (rustup blocked after #37918)

clippy has lots of lints that internally call an `intravisit::Visitor`, but the current lifetimes on `LateLintPass` methods conflicted with the required lifetimes (there was no connection between the HIR elements and the `TyCtxt`)

c8d73ea68a Implement a faster sort algorithm
This is a complete rewrite of the standard sort algorithm. The new algorithm
is a simplified variant of TimSort. In summary, the changes are:

* Improved performance, especially on partially sorted inputs.
* Performs less comparisons on both random and partially sorted inputs.
* Decreased the size of temporary memory: the new sort allocates 4x less.

mk: Switch rustbuild to the default build system

This commit switches the default build system for Rust from the makefiles to
rustbuild. The rustbuild build system has been in development for almost a year
now and has become quite mature over time. This commit is an implementation of
the proposal on [internals] which slates deletion of the makefiles on
2017-02-02.

[internals]: https://internals.rust-lang.org/t/proposal-for-promoting-rustbuild-to-official-status/4368

This commit also updates various documentation in `README.md`,
`CONTRIBUTING.md`, `src/bootstrap/README.md`, and throughout the source code of
rustbuild itself.

Forward more ExactSizeIterator methods and `is_empty` edits

- Forward ExactSizeIterator methods in more places, like `&mut I` and `Box<I>` iterator impls.
- Improve `VecDeque::is_empty` itself (see commit 4)
- All the collections iterators now have `len` or `is_empty` forwarded if doing so is a benefit. In the remaining cases, they already use a simple size hint (using something like a stored `usize` value), which is sufficient for the default implementation of len and is_empty.

3fef221514 Auto merge of #38134 - bluss:iter-nth, r=aturon
Remove Self: Sized from Iterator::nth

It is an unnecessary restriction; nth neither needs self to be sized
nor needs to be exempted from the trait object.

It increases the utility of the nth method, because type specific
implementations are available through `&mut I` or through an iterator
trait object.

It is a backwards compatible change due to the special cases of the
`where Self: Sized` bound; it was already optional to include this bound
in `Iterator` implementations.

Smarter HashMap/HashSet pre-allocation for extend/from_iter

HashMap/HashSet from_iter and extend are making totally different assumptions.

A more balanced decision may allocate half the lower hint (rounding up). For "well defined" iterators this effectively limits the worst case to two resizes (the initial reserve + one resize).

dfd3b908f5 Fix current_exe() on DragonFly (again)
This is a follow up on [this pull request][1].

Since DragonFly 4.6.1 ([this commit][2]), the "kern.proc.pathname"
sysctl works correctly, i.e. it does not return paths including a ":"
(see [here][3]). Use it and don't try to fix old versions of DragonFly!
There are not many DragonFly installations out there that we can't
control and no one is compiling Rust from source. If someone wants to
run Rust on a pre-4.6.1 DragonFly system, the ports system should
provide a patch.

`/OPT:REF,ICF` sometimes takes lots of time. It makes no sense to apply them when doing debug build. MSVC's linker by default disables these optimizations when `/DEBUG` is specified, unless they are explicitly passed.

ff261d3a6b Auto merge of #38097 - Mark-Simulacrum:fn-sig-slice, r=eddyb
Refactor ty::FnSig to contain a &'tcx Slice<Ty<'tcx>>

We refactor this in order to achieve the following wins:

 - Decrease the size of `FnSig` (`Vec` + `bool`: 32, `&Slice` + `bool`: 24).
 - Potentially decrease total allocated memory due to arena-allocating `FnSig` inputs/output; since they are allocated in the type list arena, other users of type lists can reuse the same allocation for an equivalent type list.
 - Remove the last part of the type system which needs drop glue (#37965 removed the other remaining part). This makes arenas containing `FnSig` faster to drop (since we don't need to drop a Vec for each one), and makes reusing them without clearing/dropping potentially possible.
