540fd3aa71 Auto merge of #26848 - oli-obk:const_fn_const_eval, r=pnkfelix
this has the funky side-effect of also allowing constant evaluation of function calls to functions that are not `const fn` as long as `check_const` didn't mark that function `NOT_CONST`

It's still not possible to call a normal function from a `const fn`, but let statements' initialization value can get const evaluated (this caused the fallout in the overflowing tests)

we can now do this:

```rust
const fn add(x: usize, y: usize) -> usize { x + y }
const ARR: [i32; add(1, 2)] = [5, 6, 7];
```

also added a test for destructuring in const fn args
```rust
const fn i((a, b): (u32, u32)) -> u32 { a + b } //~ ERROR: E0022
```

This is a **[breaking change]**, since it turns some runtime panics into compile-time errors. This statement is true for ANY improvement to the const evaluator.

98dcde183d mk: Re-add libgcc_s_seh-1.dll to windows dist
Although the compiler itself does not depend on this DLL the `libstdc++-6.dll`
that we're shipping does, so we still need to include it.

1220e016bd add a recursion limit for type representation
I could have added a check for explicit recursion, as irregular types
tend to cause selection errors, but I am not sufficiently sure that
cannot be bypassed.

2b000feba5 the const evaluator might run before check_const

Rust reference is a bit confusing here, because it does not explicitly mention trait objects.

996ba1d306 Auto merge of #29309 - rjbs:doc-comment-sections, r=alexcrichton
As displayed before this commit, I found the book confusing in its
explanation of `#`-led comments in `rust` blocks.  Possibly the
biggest confusion was because the many-dashes construct does not
become an HR element in the Markdown translator used, so things were
not being properly set off.

This change should more clearly show the as-rendered content as
rendered, and the as-coded content as code.

4b43e07af9 std: Slightly more robust env var handling
As discovered in #29298, `env::set_var("", "")` will panic, but it turns out
that it *also* deadlocks on Unix systems. This happens because if a panic
happens while holding the environment lock, we then go try to read
RUST_BACKTRACE, grabbing the environment lock, causing a deadlock.

Specifically, the changes made here are:

* The environment lock is pushed into `std::sys` instead of `std::env`. This
  also only puts it in the Unix implementation, not Windows where the functions
  are already threadsafe.
* The `std::sys` implementation now returns `io::Result` so panics are
  explicitly at the `std::env` level. The panic messages have also been improved
  in these situations.

278cc2f157 Auto merge of #29287 - Ryman:fn_nopat, r=alexcrichton
Previously, if you copied a signature from a trait definition such as:

```rust
fn foo<'a>(&'a Bar) -> bool {}
```

and moved it into an `impl`, there would be an error message:

"unexpected token `'a`"

Adding to the error message that a pattern is expected should help
users to find the actual problem with using a lifetime here.
