Fix example in transmute; add safety requirement to Vec::from_raw_parts
This fixes the second bullet point on #44281 and also removes some incorrect information.
Fix drain_filter doctest.
Fixes#44499.
Also change some of the hidden logic in the doctest as a regression test; two bugs in the original would now cause test failure.
Explicitly run perl for OpenSSL Configure
OpenSSL's Configure script is missing a shebang. On some platforms,
execve falls back to execution with the shell. Some other platforms,
like musl, will fail with an exec format error. Avoid this by calling
perl explicitly (since it's a perl script).
rustc: Remove `Session::dep_graph`
This commit removes the `dep_graph` field from the `Session` type according to
issue #44390. Most of the fallout here was relatively straightforward and the
`prepare_session_directory` function was rejiggered a bit to reuse the results
in the later-called `load_dep_graph` function.
Closes#44390

Analyse storage liveness and preserve it during generator transformation
This uses a dataflow analysis on `StorageLive` and `StorageDead` statements to infer where the storage of locals are live. The result of this analysis is intersected with the regular liveness analysis such that a local is can only be live when its storage is. This fixes https://github.com/rust-lang/rust/issues/44184. If the storage of a local is live across a suspension point, we'll insert a `StorageLive` statement for it after the suspension point so storage liveness is preserved. This fixes https://github.com/rust-lang/rust/issues/44179.

Remove deprecated lang items
They have been deprecated for years and there is no trace left of them in the compiler. Also removed `require_owned_box` which is dead code and other small refactorings.
Add the libstd-modifications needed for the L4Re target
This commit adds the needed modifications to compile the std crate for the L4 Runtime environment (L4Re).
A target for the L4Re was introduced in commit: c151220a84
In many aspects implementations for linux also apply for the L4Re microkernel.
Some uncommon characteristics had to be resolved:
* L4Re has no network funktionality
* L4Re has a maximum stacksize of 1Mb for threads
* L4Re has no uid or gid

Parse nested closure with two consecutive parameter lists properly
This is a followup of #44332.
---
Currently, in nightly, this does not compile:
```rust
fn main() {
let f = |_||x, y| x+y;
println!("{}", f(())(1, 2)); // should print 3
}
```
`|_||x, y| x+y` should be parsed as `|_| (|x, y| x+y)`, but the parser didn't accept `||` between `_` and `x`. This patch fixes the problem.

Extend E0623 for fn items
This fixes#44516
The below example now gives
```
error[E0623]: lifetime mismatch
--> gg.rs:3:10
|
2 | fn foo(x:fn(&u8, &u8), y: Vec<&u8>, z: &u8) {
| --- --- these two types are declared with different lifetimes...
3 | y.push(z);
| ^ ...but data from `z` flows into `y` here
error: aborting due to previous error
```
