Support excluding the generation of the standalone docs
For Ferrocene we need to exclude the generation of the standalone docs (which include the index page, which we want to replace with our own), but with the way bootstrap is currently implemented that proved not possible. This PR aims to support that.
The first problem is that the `doc::Standalone` step did two things: it generated the "standalone" documentation (which includes the index page and all the pages at the root of the documentation tree), but it also generated some files like `rust.css` and `version_info.html` that other step like `doc::TheBook` required. This meant generating the book required generating the index page, which made disabling the index page generation problematic.
The approach I took to fix the first problem is to split the step into `doc::Standalone` and `doc::SharedAssets`, with `doc::TheBook` now depending on `doc::SharedAssets`.
The second problem is that disabling the `doc::Standalone` proved to be tricky due to its path, `src/doc`. The path is accurate, as the source files for that step are `src/doc/*.md`. The problem is, bootstrap treats `--exclude` as a *suffix*, and so it also excluded the Cargo book whose source lives at `src/tools/cargo/src/doc`.
The approach I took to fix the second problem is to add the `standalone` path in addition to `src/doc`, so that you can pass `--exclude standalone`. I'm not fully happy with the solution, and the other idea I had was to just move the standalone docs source code to `src/doc/standalone`. I feel that second approach is cleaner, but also requires more changes and might require more consensus.

Improve miri_print_borrow_stacks
Per post-merge review on https://github.com/rust-lang/miri/pull/2322
* `miri_print_stacks` renamed to `miri_print_borrow_stacks`
* A bit more details in docs, clarified how unstable these functions are meant to be
* Print an `unknown_bottom` if one exists
Open question: Currently `miri_get_alloc_id` gets the expected `AllocId` for `Wildcard` pointers, but for pointers with no provenance, the function reports UB and halts the interpreter. That's definitely wrong. But what _should_ we do? Is it reasonable to check if the pointer has `None` provenance and try to get an `AllocId` for its address? That still leaves us with a failure path, which in this case might be best-handled as an ICE? I'm just not sure that changing the return type of `miri_get_alloc_id` to `Option` is a win because it complicates all normal uses of this.
Pinning tests for some `macro_rules!` errors discussed in the lang meeting
r? ``@nikomatsakis``
Mind just stamping these, since they were useful for the meeting discussion today?
Use a faster allocation size check in slice::from_raw_parts
I've been perusing through the codegen changes that result from turning on the standard library debug assertions. The previous check in here uses saturating arithmetic, which in my experience sometimes makes LLVM just fail to optimize things around the saturating operation.
Here is a demo of the codegen difference: https://godbolt.org/z/WMEqrjajW
Before:
```asm
example::len_check_old:
mov rax, rdi
mov ecx, 3
mul rcx
setno cl
test rax, rax
setns al
and al, cl
ret
example::len_check_old:
mov rax, rdi
mov ecx, 8
mul rcx
setno cl
test rax, rax
setns al
and al, cl
ret
```
After:
```asm
example::len_check_new:
movabs rax, 3074457345618258603
cmp rdi, rax
setb al
ret
example::len_check_new:
shr rdi, 60
sete al
ret
```
Running rustc-perf locally, this looks like up to a 4.5% improvement when `debug-assertions-std = true`.
Thanks ```@LegionMammal978``` (I think that's you?) for turning my idea into a much cleaner implementation.

Diagnostic derives: allow specifying multiple alternative suggestions
This allows porting `span_suggestions()` to diagnostic structs.
Doesn't work for `multipart_suggestions()` because the rank would be reversed - the struct would specify multiple spans, each of which has multiple possible replacements, while `multipart_suggestions()` creates multiple possible replacements, each with multiple spans.
suggest type annotation for local statement initialed by ref expression
In a local statement with a type declaration, if a ref expression is used on the right side and not used on the left side, in addition to removing the `&` and `&mut` on the right side, we can add them on the left side alternatively
Fixes#102892
Add eval hack in `super_relate_consts` back
Partially reverts 01adb7e98d.
This extra eval call *still* needs to happen, for example, in `normalize_param_env_or_error` when a param-env predicate has an unnormalized constant, since the param-env candidates never get normalized during candidate assembly (everywhere else we can assume that they are normalized fully).
r? `@lcnr,` though I feel like I've assigned quite a few PRs to you in the last few days, so feel free to reassign to someone else familiar with this code if you're busy!
cc #103243 (fixes the issue, but don't want to auto-close that until a backport is performed).

The change in opacity is inconsistent with most of rustdoc, which uses
default browser styles for the focus outline. Unfortunately, just using
the default focus outline here won't work, because it gets applied to
the summary itself instead of the pseudo-element "real button."
Assert if inference vars are leaking from `InferCtxt::fully_resolve`
`InferCtxt::fully_resolve` shouldn't return unresolved inference vars without us at least being aware of it, so make it an assertion now. This should only happen in cases where we used to be returning `ReEmpty`...
