`LocalInternedString::intern(x)` is preferable to

`InternedString::intern(x)` is preferable to
`Symbol::intern(x).as_interned_str()`, because the former involves one
call to `with_interner` while the latter involves two.
The case within InternedString::decode() is particularly hot, and this
change reduces the number of `with_interner` calls by up to 13%.
rustdoc: set the default edition when pre-parsing a doctest
Fixes https://github.com/rust-lang/rust/issues/59313 (possibly more? i think we've had issues with parsing edition-specific syntax in doctests at some point)
When handling a doctest, rustdoc needs to parse it beforehand, so that it can see whether it declares a `fn main` or `extern crate my_crate` explicitly. However, while doing this, rustdoc doesn't set the "default edition" used by the parser like the regular compilation runs do. This caused a problem when parsing a doctest with an `async move` block in it, since it was expecting the `move` keyword to start a closure, not a block.
This PR changes the `rustdoc::test::make_test` function to set the parser's default edition while looking for a main function and `extern crate` statement. However, to do this, `make_test` needs to know what edition to set. Since this is also used during the HTML rendering process (to make playground URLs), now the HTML renderer needs to know about the default edition. Upshot: rendering standalone markdown files can now accept a "default edition" for their doctests with the `--edition` flag! (I'm pretty sure i waffled around how to set that a long time ago when we first added the `--edition` flag... `>_>`)
I'm posting this before i stop for the night so that i can write this description while it's still in my head, but before this merges i want to make sure that (1) the `rustdoc-ui/failed-doctest-output` test still works (i expect it doesn't), and (2) i add a test with the sample from the linked issue.

Simplify BufRead::fill_buf doc example using NLL
With non-lexical lifetimes, in this example it is no longer necessary to use a block to end the borrow early.
Use iter() for iterating arrays by slice
These `into_iter()` calls will change from iterating references to
values if we ever get `IntoIterator` for arrays, which may break the
code using that iterator. Calling `iter()` is future proof.
Mark core::alloc::Layout::from_size_align_unchecked const
Makes it possible (pending stabilization of #57563 (`const_fn`)) to rewrite code like
```rust
const BUFFER_SIZE: usize = 0x2000;
const BUFFER_ALIGN: usize = 0x1000;
fn foo() {
let layout = std::alloc::Layout::from_size_align(BUFFER_SIZE, BUFFER_ALIGN)
.unwrap();
let buffer = std::alloc::alloc(layout);
}
```
to
```rust
const BUFFER_LAYOUT: std::alloc::Layout = unsafe {
std::alloc::Layout::from_size_align_unchecked(0x2000, 0x1000)
};
fn foo() {
let buffer = std::alloc::alloc(BUFFER_LAYOUT);
}
```
which (although `unsafe` is used) looks somewhat cleaner and is easier to read.
Added ignore-sgx for appropriate tests in src/test
These are all the tests that make sense to ignore when targeting fortanix-unknonw-sgx, at least in test/runpass. Other suites not yet covered.
These `into_iter()` calls will change from iterating references to
values if we ever get `IntoIterator` for arrays, which may break the
code using that iterator. Calling `iter()` is future proof.

- nalgebra: upgrade to at least 0.15, or the last patch version of 0.14
- spade: upgrade or refresh the Cargo.lock file to use version 1.7
- imageproc: upgrade to at least 0.16 (newer versions no longer use nalgebra)
implement #46205
r? @nikomatsakis
Prevent Error::type_id overrides
type_id now takes an argument that can't be named outside of the
std::error module, which prevents any implementations from overriding
it. It's a pretty grody solution, and there's no way we can stabilize
the method with this API, but it avoids the soudness issue!
Closes#60784

Update the compiler_builtins crate
This updates to 0.1.13 for `compiler_builtins`, published to fix a few
issues. The feature changes here are updated because `compiler_builtins`
no longer enables the `c` feature by default but we want to do so
through our build still.

Checking generic args after late bound region err.
Fixes#60622.
This PR fixes an ICE that occurs when a late bound region error is
emitted and that resulted in the rest of the generic arguments of a
function not being checked.
For example, you could specify a generic type parameter `T` in a function
call `foo<'_, T>()` to a function that doesn't have a generic type
parameter.
Since an error wasn't emitted from the function, compilation
continued to parts of typeck that didn't expect a generic type argument
in a call for a function that didn't have any generic type arguments.
