Fix `suspicious_xor_used_as_pow.rs` performance

The original `suspicious_xor_used_as_pow` lint had poor performance, so I fixed that + a little refactor so that module is readable.

**107 millis. -> 106 millis.** Using `SPEEDTEST` on Rust's VMs

This idea comes from #11238. I've put the lint in `pedantic` as it might trigger numerous positives (three in Clippy itself).

Add `sym::iter_mut` + `sym::as_mut_ptr` for Clippy

We currently have `sym::iter` and `sym::iter_repeat`, this PR adds `sym::iter_mut` as it's useful for https://github.com/rust-lang/rust-clippy/pull/11038 and another Clippy lint, it also adds `sym::as_mut_ptr` as it's useful for https://github.com/rust-lang/rust-clippy/pull/10962.

ed2ec819e9 Auto merge of #114054 - oli-obk:cleanups, r=estebank 
Split some functions with many arguments into builder pattern functions

r? `@estebank`

This doesn't resolve all of the ones in rustc, mostly because I need to do other cleanups in order to be able to use some builder derives from crates.io

Works around https://github.com/rust-lang/rust/issues/90672 by making `x test rustfmt --bless` format itself instead of testing that it is formatted
