Remove #![allow(rustc::potential_query_instability)] from rustc_infer
Related to #84447
This PR probably needs to be benchmarked to check for regressions.
These lines (including the FIXME comment) were added to windows_gnu_base.rs in cf2c492ef8 but windows_gnullvm_base.rs was not updated. This resulted in an error `LLVM ERROR: dwo only supported with ELF and Wasm` attempting to build on aarch64-pc-windows-gnullvm.

LLVM 16: Update RISCV data layout
The RISCV data layout was changed in 974e2e690b.
This updates all `riscv64*` targets, though I don't really know what the difference between the `gc` and `imac` ones is.
Passes `x test codegen` at LLVM head and with the currently bundled LLVM version. Without this patch, some tests fail with:
> error: internal compiler error: compiler/rustc_codegen_llvm/src/context.rs:192:13: data-layout for target `riscv64gc-unknown-none-elf`, `e-m:e-p:64:64-i64:64-i128:128-n64-S128`, differs from LLVM target's `riscv64` default layout, `e-m:e-p:64:64-i64:64-i128:128-n32:64-S128
Add type_array to BaseTypeMethods
Moved `type_array` function to `rustc_codegen_ssa::BaseTypeMethods` trait. This allows using normal `alloca` function to create arrays as suggested in https://github.com/rust-lang/rust/pull/104022.

rustdoc: various cross-crate reexport fixes
Fixes for various smaller cross-crate reexport issues.
The PR is split into several commits for easier review. Will be squashed after approval.
Most notable changes:
* We finally render late-bound lifetimes in the generic parameter list of cross-crate functions & methods.
Previously, we would display the re-export of `pub fn f<'s>(x: &'s str) {}` as `pub fn f(x: &'s str)`
* We now render unnamed parameters of cross-crate functions and function pointers as underscores
since that's exactly what we do for local definitions, too. Mentioned as a bug in #44306.
* From now on, the rendering of cross-crate trait-object types is more correct:
* `for<>` parameter lists (for higher-ranked lifetimes) are now shown
* the return type of `Fn{,Mut,Once}` trait bounds is now displayed
Regarding the last list item, here is a diff for visualization (before vs. after):
```patch
- dyn FnOnce(&'any str) + 'static
+ dyn for<'any> FnOnce(&'any str) -> bool + 'static
```
The redundant `+ 'static` will be removed in a follow-up PR that will hide trait-object lifetime-bounds if they coincide with [their default](https://doc.rust-lang.org/reference/lifetime-elision.html#default-trait-object-lifetimes) (see [Zulip discussion](https://rust-lang.zulipchat.com/#narrow/stream/266220-rustdoc/topic/clean_middle_ty.3A.20I.20need.20to.20add.20a.20parameter/near/307143097)). `FIXME(fmease)`s were added.
