They are also removed from the prelude as per the decision in
https://github.com/rust-lang/rust/issues/87228.
stdarch and compiler-builtins are updated to work with the new, stable
asm! and global_asm! macros.

This allows the format_args! macro to keep the pre-expansion code out of
the unsafe block without doing gymnastics with nested `match`
expressions. This reduces codegen.

Remove unstable `--pretty` flag
It doesn't do anything `--unpretty` doesn't, and due to a bug, also
didn't show up in `--help`. I don't think there's any reason to keep it
around, I haven't seen anyone using it.
Closes https://github.com/rust-lang/rust/issues/36473.
|

For example, this code:
$arg:expr
used to be pretty-printed as:
$ arg : expr
but is now pretty-printed as:
$arg : expr
|

fix pretty print for `loop`

Use HTTPS links where possible
While looking at #86583, I wondered how many other (insecure) HTTP links were in `rustc`. This changes most other `http` links to `https`. While most of the links are in comments or documentation, there are a few other HTTP links that are used by CI that are changed to HTTPS.
Notes:
- I didn't change any to or in licences
- Some links don't support HTTPS :(
- Some `http` links were dead, in those cases I upgraded them to their new places (all of which used HTTPS)

Re-add support for parsing (and pretty-printing) inner-attributes in match body
Re-add support for parsing (and pretty-printing) inner-attributes within body of a `match`.
In other words, we can do `match EXPR { #![inner_attr] ARM_1 ARM_2 ... }` again.
I believe this unbreaks the only four crates that crater flagged as broken by PR #83312.
(I am putting this up so that the lang-team can check it out and decide whether it changes their mind about what to do regarding PR #83312.)

In addition to making the output look nicer for all crates, this also
aligns the pretty-printing output with what the `rental` crate expects.
This will allow us to eventually disable a backwards-compat hack in a
follow-up PR.

They were originally called "opt-in, built-in traits" (OIBITs), but
people realized that the name was too confusing and a mouthful, and so
they were renamed to just "auto traits". The feature flag's name wasn't
updated, though, so that's what this PR does.
There are some other spots in the compiler that still refer to OIBITs,
but I don't think changing those now is worth it since they are internal
and not particularly relevant to this PR.
Also see <https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/opt-in.2C.20built-in.20traits.20(auto.20traits).20feature.20name>.

If a symbol name can only be imported from one place for a type, and
as long as it was not glob-imported anywhere in the current crate, we
can trim its printed path and print only the name.
This has wide implications on error messages with types, for example,
shortening `std::vec::Vec` to just `Vec`, as long as there is no other
`Vec` importable anywhere.
This adds a new '-Z trim-diagnostic-paths=false' option to control this
feature.
On the good path, with no diagnosis printed, we should try to avoid
issuing this query, so we need to prevent trimmed_def_paths query on
several cases.
This change also relies on a previous commit that differentiates
between `Debug` and `Display` on various rustc types, where the latter
is trimmed and presented to the user and the former is not.

This commit adds a regression test for #74745. While a
`ignore-tidy-trailing-lines` header is required, this doesn't stop the
test from reproducing, so long as there is no newline at the end of the
file.
However, adding the header comments made the test fail due to a bug in
pprust, fixed in the previous commit.

This commit adjusts the pretty printing of mixed comments so that the
initial zero-break isn't emitted at the beginning of the line. Through
this, the `block-comment-wchar` test can have the `pp-exact` file
removed, as it no longer converges from pretty printing of the source.

This commit adds support to rustc_ast_pretty for multiline comments that
start and end within a line of source code.

Allow the `asm!` macro to accept a series of template arguments, and
interpret them as if they were concatenated with a '\n' between them.
This allows writing an `asm!` where each line of assembly appears in a
separate template string argument.
This syntax makes it possible for rustfmt to reliably format and indent
each line of assembly, without risking changes to the inside of a
template string. It also avoids the complexity of having the user
carefully format and indent a multi-line string (including where to put
the surrounding quotes), and avoids the extra indentation and lines of a
call to `concat!`.
For example, rewriting the second example from the [blog post on the new
inline assembly
syntax](https://blog.rust-lang.org/inside-rust/2020/06/08/new-inline-asm.html)
using multiple template strings:
```rust
fn main() {
let mut bits = [0u8; 64];
for value in 0..=1024u64 {
let popcnt;
unsafe {
asm!(
" popcnt {popcnt}, {v}",
"2:",
" blsi rax, {v}",
" jz 1f",
" xor {v}, rax",
" tzcnt rax, rax",
" stosb",
" jmp 2b",
"1:",
v = inout(reg) value => _,
popcnt = out(reg) popcnt,
out("rax") _, // scratch
inout("rdi") bits.as_mut_ptr() => _,
);
}
println!("bits of {}: {:?}", value, &bits[0..popcnt]);
}
}
```
Note that all the template strings must appear before all other
arguments; you cannot, for instance, provide a series of template
strings intermixed with the corresponding operands.
In order to get srcloc mappings right for macros that generate
multi-line string literals, create one line_span for each
line in the string literal, each pointing to the macro.
Make `rustc_parse_format::Parser::curarg` `pub`, so that we can
propagate it from one template string argument to the next.

They used to be covered by `optin_builtin_traits` but negative impls
are now applicable to all traits, not just auto traits.
This also adds docs in the unstable book for the current state of auto traits.

Expansion-driven outline module parsing
After this PR, the parser will not do any conditional compilation or loading of external module files when `mod foo;` is encountered. Instead, the parser only leaves `mod foo;` in place in the AST, with no items filled in. Expansion later kicks in and will load the actual files and do the parsing. This entails that the following is now valid:
```rust
#[cfg(FALSE)]
mod foo {
mod bar {
mod baz; // `foo/bar/baz.rs` doesn't exist, but no error!
}
}
```
Fixes https://github.com/rust-lang/rust/issues/64197.
