Similar to rust-lang/rust#100445, this adapts the new test added by rust-lang/rust#99207 to some relatively recent [LLVM changes](https://github.com/llvm/llvm-project/commit/057cabd997aeaef136e1e14f2ee645bd5bb197dd) that removed the function name from msan messages.

Rollup merge of #101595 - ehuss:fix-ice-flag-report, r=tmiasko
Fix ICE report flags display.
#92310 made some changes to the ICE report that displays the rustc flags, but it introduced a bug where a flag like `-Z incremental-verify-ich=yes` was being treated as-if it was `-Cincremental`. This corrupted the output and made it confusing. The cause was using `starts_with` instead of properly splitting the option.
For example, with the command like `rustc foo.rs -Cincremental=/tmp/a -Zincremental-verify-ich=yes --crate-type lib` would previously look like:

Use RelocModel::Pic for UEFI targets
In https://github.com/rust-lang/rust/pull/100537, the relocation model for UEFI targets was changed from PIC (the default value) to
static. There was some dicussion of this change here: https://github.com/rust-lang/rust/pull/100537#discussion_r952363012
It turns out that this can cause compilation to fail as described in https://github.com/rust-lang/rust/issues/101377, so switch back to PIC.
Auto merge of #99916 - dpaoliello:stablizerawdylib, r=wesleywiser
Stabilize raw-dylib for non-x86
This stabilizes the `raw-dylib` and `link_ordinal` features (#58713) for non-x86 architectures (i.e., `x86_64`, `aarch64` and `thumbv7a`):
* Marked the `raw_dylib` feature as `active`.
* Marked the `link_ordinal` attribute as `ungated`.
* Added new errors if either feature is used on x86 targets without the `raw_dylib` feature being enabled.
* Updated tests to only set the `raw_dylib` feature when building for x86.

Fix the example code and doctest for Formatter::sign_plus
The provided example to the `sign_plus` method on `fmt` was broken, it displays the `-` sign twice for negative numbers.
This pull request should fix the issue by `.abs()` ing the number so that the negative sign appears only once. It is just one possible solution to the issue, not sure if it's the best. However, this one will behave as expected when combined with fill and alignment operators.

Restore old behaviour on broken UNC paths

This PR moves the tooltip into example-wrap, simplifying several overly-complex aspects of how these tooltips work:
* The mousover javascript can be removed, because hovering example-wrap can style the tooltip inside.
* The sibling selecor can be removed, because hovering the tooltip also hovers the wrapper, which can hover the codeblock itself.
* The relative positioning of the `<li>` tag, which was added in https://github.com/rust-lang/rust/commit/e861efd9f9ca45c1048a256812dfe8faffbb1367 to fix the positioning of the code tooltip, can now be removed, because example-wrap itself already has relative positioning.

Update LLVM used in x86 CI dist builds to `15.0.0`
LLVM 15.0.0 has been released, so we can use it in CI builds. We need (at least) LLVM 15 for BOLT, and we regularly update to most recent stable versions. It would also be good to first see the perf. effect of upgrading by itself, to have a better baseline for BOLT.
Rollup merge of #101556 - compiler-errors:tweak-generator-print, r=jackh726
Tweak future opaque ty pretty printing
1. The `Return` type of a generator doesn't need to be a lang item just for diagnostic printing of types
2. We shouldn't suppress the `Output = Ty` of a opaque future if the type is a int or float var.
Auto merge of #101224 - compiler-errors:rpitit, r=oli-obk
Initial implementation of return-position `impl Trait` in traits
* Create a new item kind, called `ImplTraitPlaceholder`, which is used to lower `ast::TyKind::ImplTrait` in trait method returns.
* This item is the child of the trait method, which simplifies the way we calculate bounds and stuff.
* Use the def-id of this type to construct a projection type that we use during astconv for the return type of the trait method signature.
* Implement logic to normalize this `ImplTraitPlaceholder` projection type when we know its concrete impl (this is pretty limited currently, but really there are no other selection candidates that make sense -- for now!)
* Check that the `impl Trait`'s bounds are satisfied on the concrete type provided in the impl.
This is obviously nowhere near complete, but I wanted to at least get some initial support landed so we can start playing around with it.
What works:
* async fn in trait and RPITIT, including multiple `impl Trait`s and `impl Trait` nested in associated type bindings, like `impl Future<Output = impl Sized>`

Fix `range_{plus,minus}_one` bad suggestions
Fixes #9431.
The current `range_plus_one` and `range_minus_one` suggestions are completely incorrect when macros are involved.
This commit resolves this by disabling the lints for any range expression that is expanded from a macro. The reasons for this are that it is very difficult to create a correct suggestion in this case and that false negatives are less important for pedantic lints.
changelog: Fix `range_{plus,minus}_one` bad suggestions
This CSS was added in 5e01ba36c9f1037c4cf3e7421413fc6c41f85d05, and served to override CSS right above it that set a 5px padding for several kinds of buttons in the same toolbar:
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.

Auto merge of #101437 - compiler-errors:erase-normalize-ordering, r=tmandry
Normalize before erasing late-bound regions in `equal_up_to_regions`
Normalize erasing regions **first**, before passing the type through a `BottomUpFolder` which erases late-bound regions too.
The root cause of this issue is due to 96d4137deed6c52c6db2dd19568c37d1c160f1e7, which removes a `normalize_erasing_regions` that happens before this call to `equal_up_to_regions`. While reverting that commit might be a fix, I think it was suspicious to be erasing late-bound regions first _then_ normalizing types in the first place in `equal_up_to_regions`.
-----
I am tempted to ask the reviewer to review and `r+` this without a UI test, since the existing issues that I think this fixes are all incredibly difficult to minimize (anything hyper/warp related, given the nature of those libraries :sweat:) or impossible to reproduce locally (the miri test), namely:
* This recently reported issue with tokio + warp: #101430
* This issue from `@RalfJung` about Miri being broken: #101344
* This additional issue reported in a comment by `@tmandry` (issue with fuchsia + hyper): https://github.com/rust-lang/rust/issues/101344#issuecomment-1235974564
I have locally verified that the repro in #101430 is fixed with this PR, but after a couple of hours of attempting to minimize this error and either failing to actually repro the ICE, or being overwhelmed with the number of traits and functions I need to inline into a UI test, I have basically given up. Thoughts are appreciated on how best to handle this.
r? `@oli-obk` who is at the intersection of MIR and types-related stuff who may be able to give advice :sweat_smile:

* Some code clean-ups, including
* add `lang_item_for_op` to turn a `Op` into a `DefId`
* avoid `SourceMap` because we don't really need to render an expr
* Remove `TypeParamVisitor` in favor of just checking `ty.has_param_types_or_consts` -- this acts a bit differently, but shouldn't cause erroneous suggestions (actually might generalize them a bit)
* We now suggest `Output = Ty` in the `where` clause suggestion when we fail to add `Struct<T>` and `T`.
I can split this out into more PRs if needed, but they're all just miscellaneous generalizations, changes, and nitpicks I saw when messing with this operator code.

# Description
This is the second part of the `rustc_session` [migration](https://github.com/rust-lang/rust/issues/100717#issuecomment-1220279883).
**Please only review this [commit](https://github.com/rust-lang/rust/pull/101041/commits/501858195734ec77f6b121ef753b03c40645df23) that belongs to the part 2. The other ones are from the PR [#100753](https://github.com/rust-lang/rust/pull/100753) that is not yet merged.**
In this PR, we migrate the files `session.rs` and `config.rs`.
Please not that we have to `allow` the lints rules in some functions from `session.rs` because they are (at least I believe) part of the diagnostic machinery.
