371994e0d8 Auto merge of #112314 - ferrocene:pa-core-alloc-abort, r=bjorn3 
Ignore `core`, `alloc` and `test` tests that require unwinding on `-C panic=abort`

Some of the tests for `core` and `alloc` require unwinding through their use of `catch_unwind`. These tests fail when testing using `-C panic=abort` (in my case through a target without unwinding support, and `-Z panic-abort-tests`), while they should be ignored as they don't indicate a failure.

This PR marks all of these tests with this attribute:

```rust
#[cfg_attr(not(panic = "unwind"), ignore = "test requires unwinding support")]
```

I'm not aware of a way to test this on rust-lang/rust's CI, as we don't test any target with `-C panic=abort`, but I tested this locally on a Ferrocene target and it does indeed make the test suite pass.

Add MVP suggestion for `unsafe_op_in_unsafe_fn`

Rebase of https://github.com/rust-lang/rust/pull/99827

cc tracking issue https://github.com/rust-lang/rust/issues/71668

No real changes since the original PR, just migrated the new suggestion to use fluent messages and added a couple more testcases, AFAICT from the discussion there were no outstanding changes requested.

loongarch64-unknown-none*: Set default relocation model to static

This PR sets the default relocation model to `static` for `loongarch64-unknown-none*` targets. This change aims to streamline the development of the bare-metal project by removing the need for the executable program loader to implement relocation.

Add help for trying to do C-like pointer arithmetics

This PR adds help messages for these cases:

```rust
fn main() {
    let ptr1: *const u32 = std::ptr::null();

    let a = ptr1 + 5;
    let b = ptr1 - 5;
    let c = ptr2 - ptr1;
    let d = ptr1[5];
}
```
