The IL module doesn't take a session variable, so its logging and session-state
actions are limited and/or global. Fix this.

The variable `output` or `out_filename` becomes (null) after the definition
of `fn unlib`. Move the function defintion to the beginning seems
prevent the crash on Linux.

Good morning,

It's taken a long time, but I finally am almost done freeing libsyntax of `vecs_implicitly_copyable` in this pull request, but I'm running into some issues. I've confirmed that all but the last commit (which only disables `vecs_implicitly_copyable` pass the `check` tests. The last commit errors with this message, which makes no sense to me:

```
/Users/erickt/rust/rust/src/libcore/num/f32.rs:35:37: 35:43 error: expected `,` but found `=`

There also a bunch of new warnings that I haven't cleaned up yet: https://gist.github.com/erickt/5048251.

@nikomatsakis thought there might be some scary bug in the parser caused by moving a vector in the parser instead of copying it, which is why I'm filing this pull request before it's ready. Thanks for any help!

As per #2521. Inlining seems to improve performance slightly:

                 Inlined          Not Inlined
    x86:         13.5482            14.4112
    x86_64:      17.4712            18.0696

(Average of 5 runs timed with `time`)

```Rust

fn foo() -> int {
    int::from_str(~"28098").unwrap()
}

fn main() {
    for 1000000.times {
        foo();
        foo();
        foo();
        foo();
        foo();
    }
}
```

All run on:

    Linux 3.2.0-0.bpo.4-amd64 #1 SMP Debian 3.2.35-2~bpo60+1 x86_64 GNU/Linux

The MIPS and ARM bits I didn't inline since I'm not as familiar with them and I also can't test them. All green on try.

Repair several `riscv64gc-unknown-linux-gnu` codegen tests

Together with [email protected], we've been starting to explore improving the state of the `riscv64gc-unknown-linux-gnu` target. Additionally, I'm looking to add support for this platform in [Ferrocene](https://github.com/ferrocene/ferrocene) ([Related PR](ferrocene/ferrocene#618)).

While running the test suite, we noted several tests were failing.

It appears that several of the riscv64gc-unknown-linux-gnu codegen tests have not been updated in some time and seem to have experienced a small amount of bitrot.

After speaking with `@workingjubilee` (as I have little expertise in LLVM codegen) I believe these changes to be correct.

### `tests/codegen/riscv-abi/call-llvm-intrinsics.rs`

I believe this change does not alter what the test is testing and is harmless.

### `tests/codegen/riscv-abi/riscv64-lp64d-abi.rs`

The changes largely mirrors those from loongarch64:

https://github.com/rust-lang/rust/blob/550d1b4fb6de23990f4108815c3b1a9d1659e5c4/tests/codegen/loongarch-abi/loongarch64-lp64d-abi.rs#L13-L15

https://github.com/rust-lang/rust/blob/550d1b4fb6de23990f4108815c3b1a9d1659e5c4/tests/codegen/loongarch-abi/loongarch64-lp64d-abi.rs#L259-L261

https://github.com/rust-lang/rust/blob/550d1b4fb6de23990f4108815c3b1a9d1659e5c4/tests/codegen/loongarch-abi/loongarch64-lp64d-abi.rs#L263-L267

### `tests/codegen/riscv-abi/riscv64-lp64f-lp64d-abi.rs`

The changes largely mirror that from loongarch64 or llvm:

https://github.com/rust-lang/rust/blob/550d1b4fb6de23990f4108815c3b1a9d1659e5c4/tests/codegen/loongarch-abi/loongarch64-lp64d-abi.rs#L13-L26

https://github.com/rust-lang/llvm-project/blob/5399a24c66cb6164cf32280e7d300488c90d5765/clang/test/CodeGen/RISCV/riscv64-abi.c#L612-L617

### `tests/ui/debuginfo/debuginfo-emit-llvm-ir-and-split-debuginfo.rs`

The test is ignored since `-Csplit-debuginfo=unpacked` is not supported on this platform. Context can be found in #120518.

## Reproducing the failures

Using a `config.toml` with the following:

```toml
# ...

target = [
   # ...
   "riscv64gc-unknown-linux-gnu",
]
```

> [!NOTE]
> You may need to install a RICV-V toolchain! We get ours from [here](https://www.embecosm.com/resources/tool-chain-downloads/#riscv-linux).
>
> If you are using an old (20.04) Ubuntu container the compiler in the repositories (`gcc-riscv64-linux-gnu`) won't work!

Run the following test suite:

```bash
./x.py test tests/codegen
```

Tell users not to file a bug when using internal library features

Actually fixes #97501. I don't think we should suppress the suggestion to add `#![feature(..)]`, though I guess I could be convinced otherwise.

r? `@Nilstrieb` cc `@RalfJung`

Didn't add a test b/c I don't think we test this for lang features either, but I can confirm it does work.

```
warning: the feature `core_intrinsics` is internal to the compiler or standard library

better implementation of signed div_floor/ceil

Tracking issue for signed `div_floor`/`div_ceil`: #88581.

This PR improves the implementation of those two functions by adding a better branchless algorithm. Side-by-side comparison of `i32::div_floor` on x86-64:

Optimize `Box::default` and `Arc::default` to construct more types in place

Both the `Arc` and `Box` `Default` impls currently call `T::default()` before allocating, and then moving the resulting `T` into the allocation.

Most `Default` impls are trivial, which should in theory allow
LLVM to construct `T: Default` directly in the `Box` allocation when calling
`<Box<T>>::default()`.

However, the allocation may fail, which necessitates calling `T`'s destructor if it has one.
If the destructor is non-trivial, then LLVM has a hard time proving that it's
sound to elide, which makes it construct `T` on the stack first, and then copy it into the allocation.

Change both of these impls to allocate first, and then call `T::default` into the uninitialized allocation, so that LLVM doesn't have to prove that it's sound to elide the destructor/initial stack copy.

For example, given the following Rust code:

```rust
#[derive(Default, Clone)]
struct Foo {
    x: Vec<u8>,
    z: String,
    y: Vec<u8>,
}

#[no_mangle]
pub fn src() -> Box<Foo> {
    Box::default()
}
```

This should help with the rust-analyzer setup which issues many individual `./x check` calls. There's more that could be done but these were the lowest-hanging fruits that I saw.

The space after `i64` in the original regex made the regex not match for
