Hello, beginner here, impassioned by the project. This pull request addresses issue #7588, which highlights the prevalent use of unsafe pointer offsets in the aarch64 relocation code within the cranelift-jit component. The current approach frequently casts these unsafe offsets to usize or isize types, suggesting an opportunity to improve code safety and readability by performing these casts eagerly. Please feel free to correct any noob mistakes. I'm eager to learn and contribute more effectively!

Please revert this commit. Dependency updates require reviewing the changes in those dependencies by a trusted reviewer, which cargo-vet enforces. Because no such review has been done, CI would fail once it runs.

This would loose optimizations and isn't more correct.
.offset()is unsafe as it is UB to go out of bounds, but if the calculation goes out of bounds, this crate would produce UB anyway, except now sanitizers no longer know that going out of bounds is invalid and thus wouldn't trigger at the root cause of the UB.
