No functional changes intended. Adapts PassWrapper for two recent LLVM API changes: * llvm/llvm-project@e7bac3b * llvm/llvm-project@93600eb * llvm/llvm-project@5e38b2a

This was added in 51f26ac to help with the display of an `<h3>` tag that has a `<span class='in-band'>` inside. The way implementation lists were rendered was changed in 34bd2b8 to have `<code class='in-band'>`, making this CSS unused. Then it was turned into a `<div>` in 9077d54 without issue. Finally, the header itself acquired the `in-band` class in 76a3b60.

This was added in 9077d54 to override the style on `<div>` tags that were acting as headers. These `<div>` tags were replaced with `<section>` tags in 32f6260, but this CSS was probably already redundant even then (the headers had already been replaced with real `<h3>` and `<h4>` tags in 76a3b60).

This CSS was added in 5e01ba3, and served to override CSS right above it that set a 5px padding for several kinds of buttons in the same toolbar. The CSS that it overrode is still there, but now it only applies to `#settings-menu > a`, so there's nothing to override.

Fix hermit warnings This fixes two `unused_imprt` and one `dead_code` warning for hermit.

…li-obk Introduce lowering_arena to avoid creating AST nodes on the fly `@oli-obk` requested this and other changes as a way of simplifying rust-lang#101345. This is just going to make the diff of rust-lang#101345 smaller. r? `@oli-obk` `@cjgillot`

llvm-wrapper: adapt for LLVM API changes No functional changes intended. Adapts PassWrapper for a few recent LLVM API changes: * llvm/llvm-project@e7bac3b * llvm/llvm-project@93600eb * llvm/llvm-project@5e38b2a Note that `ModuleMemorySanitizerPass` was renamed back to its pre-14 name, `MemorySanitizerPass`, hence the funky `#if LLVM_VERSION_GE(14, 0) && LLVM_VERSION_LT(16, 0)` guard.

All these changes are just noise.

cranelift-codegen and keccak are noisy right now, so those improvements aren't real.
The coercions regression is only for a single profile/scenario combination, so I don't think it's meaningful.
