Commit 2550530 has extended the `precedence` lint to include bitmasking and shift operations. The lint is warn by default, and this generates many hits, especially in embedded or system code, where it is very idiomatic to use expressions such as `1 << 3 | 1 << 5` without parentheses. This commit splits the recent addition into a new lint, which is put into the "restriction" category, while the original one stays in "complexity", because mixing bitmasking and arithmetic operations is less typical.

Agree. I'll merge this right away without a FCP because I understand that we're reducing a lot of churn, and we want to do that quickly. |

Mostly cleaning up some more map_ors, but the one big change of note is temporarily allowing the clippy:precedence lint. Previously this lint only applied to arithmetic operations, however a change in 1.85 causes it to apply to bitwise operations as well. This is overly noisy, and unnecessary. And the clippy maintainers agree, as they've since split out this change into a separate lint, precedence_bits, that is allow-by-default. However that split will not be present until 1.86. See rust-lang/rust-clippy#14115 for details on that.

- Allow clippy::precedence which includes bitmasking and shift operations in Rust 1.85. This behaviour will be reverted in 1.86: rust-lang/rust-clippy#14115.
