update polonius-engine
This updates polonius-engine to [version 0.7.0](https://github.com/rust-lang/polonius/blob/master/RELEASES.md#v070), which adds a hybrid algorithm that starts off with performing a cheaper, location-insensitive analysis before proceeding with the full analysis.

Increase `Span` from 4 bytes to 8 bytes.
This increases the size of some important types, such as `ast::Expr` and
`mir::Statement`. However, it drastically reduces how much the interner
is used, and the fields are more natural sizes that don't require bit
operations to extract.
As a result, instruction counts drop across a range of workloads, by as
much as 10% for `script-servo` incremental builds.
Peak memory usage goes up a little for some cases, but down by more for
some other cases -- as much as 18% for non-incremental builds of
`packed-simd`.
The commit also:
- removes the `repr(packed)`, because it has negligible effect, but can
cause undefined behaviour;
- replaces explicit impls of common traits (`Copy`, `PartialEq`, etc.)
with derived ones.

pnkfelix:revert-pr-59401-to-fix-emit-stack-sizes-gc-sections-ld-gold-bug, r=alexcrichton
Revert "compile crates under test w/ -Zemit-stack-sizes"
Revert PR #59401 to fix issue #59652 (a stable-to-beta regression).
This is result of squashing two revert commits:
Revert "compile all crates under test w/ -Zemit-stack-sizes"
This reverts commit 7d365cf27f4249fc9b61ba8abfc813abe43f1cb7.
Revert "bootstrap: build compiler-builtins with -Z emit-stack-sizes"
This reverts commit 8b8488ce8fc047282e7159343f30609417f9fa39.
----
(My intention is that someone can re-add this code again later, either after the `ld.gold` issue itself is fixed, or with safe-guards to check whether `ld.gold` is in use and then issuing warnings about the problems here when they arise.)

Don't generate empty json variables

Clean up handling of `-Z pgo-gen` commandline option.
This PR adapts the `-Z pgo-gen` flag to how Clang and GCC handle the corresponding `-fprofile-generate` flag. In particular, the flag now optionally takes a directory to place the profiling data in and allows to omit the argument (instead of having to pass an empty string).

Exclude profiler-generated symbols from MSVC __imp_-symbol workaround.
LLVM's profiling instrumentation adds a few symbols that are used by the profiler runtime. Since these show up as globals in the LLVM IR, the compiler generates `dllimport`-related `__imp_` stubs for them. This can lead to linker errors because the instrumentation symbols have weak linkage or are in a comdat section, but the `__imp_` stubs aren't.
Instead of trying to replicate the linkage/comdat setup for the stubs, this PR just excludes the profiler-related symbols from stub-generation since they aren't supposed to be referenced via `__declspec(dllimport)` anywhere anyway.
r? @alexcrichton
EDIT: I considered making this more general, i.e. inferring from the symbol name if it is a Rust symbol or not. But then I figured out that that would yield false negatives for `#[no_mangle]` et al, so I went with a blacklist approach.

std: Add `{read,write}_vectored` for more types
This commit implements the `{read,write}_vectored` methods on more types
in the standard library, namely:
* `std::fs::File`
* `std::process::ChildStd{in,out,err}`
* `std::io::Std{in,out,err}`
* `std::io::Std{in,out,err}Lock`
* `std::io::Std{in,out,err}Raw`
Where supported the OS implementations hook up to native support,
otherwise it falls back to the already-defaulted implementation.

Retire `IsNotConst` naming
This naming scheme caused a lot of confusion lately (including ICEs) due to misrefactored code. Also clean up the initialization code for said flag.

Copy book.toml unstable book generator
Solves https://github.com/rust-lang/rust/issues/59554 and adds a book title to the unstable book.
I assume that [copy_recursive](https://github.com/rust-lang/rust/blob/acd8dd6a50d505057a7d7ad8d0d7a4c2bd274200/src/tools/unstable-book-gen/src/main.rs#L105) will take files regardless of their type (`.md` or `.toml`).
Although I had a hard time time testing it. A second pair of eyes is definitely needed.

Use normal newtype_index macro for MIR dataflows
* Makes the definition of these structs contain `struct IndexName`
* Avoids having an offset by removing high values, rather than 0
* Implements some traits for us.
