but from_proto::offset() doesn't implement this.
A client might for example request code actions for a whole line by sending
Position::character=99999. I don't think there is ever a reason (besides laziness) why the
client can't specify the line length instead but I guess we should not crash but follow protocol.
Technically it should be a warning, not an error but warning is not shown by default so keep
it at error I guess.

internal: fix lldb-dap unconditionally calling rustc
Fixes https://github.com/rust-lang/rust-analyzer/issues/18318. I also took the opportunity to refactor how `discoverSourceFileMap` worked—it now returns a type instead of mutating a map in place.
I tested this change using the LLDB DAP extension. I needed to set `"lldb-dap.executable-path": "/Applications/Xcode.app/Contents/Developer/usr/bin/lldb-dap"` for everything to work, however, but once I did, was able to successfully debug a test.

Not sure how to update Cargo.lock (lib/README.md doesn't say how).

Rustfmt `for<'a> async` correctly
In #127054, we decided to move the trait bound modifier for `async for<'a> Fn()` to `for<'a> async Fn()`. This wasn't adjusted in rustfmt, so this PR implements that. It also requires consolidating the bound formatting into the `Rewrite` impl for `PolyTraitRef`.

Fix unnecessary nesting in run-make test output directories
Run-make tests were using `output_base_name` to determine their output directory, which results in a redundant subdirectory (e.g. `$build/test/run-make/<foo>/<foo>/`) because that method is intended to produce the name of an individual file.
The previous attempt to fix this double-nesting tried adding a special case in `output_base_dir`, which had the side-effect of breaking up-to-date checking for run-make tests, and had to be reverted in #131681.
The fix is simply to call `output_base_dir` directory, which gives the desired directory without any redundant part.

Remove `GenKillAnalysis`
There are two kinds of dataflow analysis in the compiler: `Analysis`, which is the basic kind, and `GenKillAnalysis`, which is a more specialized kind for gen/kill analyses that is intended as an optimization. However, it turns out that `GenKillAnalysis` is actually a pessimization! It's faster (and much simpler) to do all the gen/kill analyses via `Analysis`. This lets us remove `GenKillAnalysis`, and `GenKillSet`, and a few other things, and also merge `AnalysisDomain` into `Analysis`. The PR removes 500 lines of code and improves performance.

Fix most ui tests on emscripten target
To fix the linker errors, we need to set the output extension to `.js` instead of `.wasm`. Setting the output to a `.wasm` file puts Emscripten into standalone mode which is effectively a distinct target. We need to set the runner to be `node` as well.
This fixes most of the ui tests. I fixed 4 additional tests with simple problems:
- `intrinsics/intrinsic-alignment.rs` -- Two `#[cfg]` macros match for Emscripten so we got duplicate definition
- `structs-enums/rec-align-u64.rs` -- same problem
- `issues/issue-12699.rs` -- hangs so I disabled it
- `process/process-sigpipe.rs` -- Not expected to work on Emscripten so I disabled it
Resolves#131666.
There are 7 more failing tests. I'll try to investigate more and see if I can fix them or at least understand why they happen.
- abi/numbers-arithmetic/return-float.rs (problem with [wasm treatment of noncanonical floats](https://webassembly.github.io/spec/core/exec/numerics.html#nan-propagation)?)
- async-await/issue-60709.rs -- linker error related to memcpy. Possible Emscripten bug?
- backtrace/dylib-dep.rs -- Says "Not supported"
- backtrace/line-tables-only.rs -- Says "Not supported"
- no_std/no-std-unwind-binary.rs -- compiler says `error: lang item required, but not found: eh_catch_typeinfo`
- structs-enums/enum-rec/issue-17431-6.rs -- One of the two compiler errors is missing
- test-attrs/test-passed.rs

Some float methods are now `const fn` under the `const_float_methods` feature gate.
In order to support `min`, `max`, `abs` and `copysign`, the implementation of some intrinsics had to be moved from Miri to rustc_const_eval.
Add `&pin (mut|const) T` type position sugar

Resolved python deprecation warning in publish_toolstate.py
`utcnow()` is deprecated in favor of passing a timezone to `now()`. `utcnow()` would return a tz-naive datetime, while this returns a tz-aware datetime. For the purposes of the formatting we do, these are the same.
Fix up-to-date checking for run-make tests
This special case in `output_base_dir` had the unfortunate side-effect of causing all run-make tests to share the same `stamp` file. So as soon as any one of them succeeded, all of the failed tests would be incorrectly considered up-to-date and would no longer run in subsequent test invocations.
Fixes#129971.

Move polarity into `PolyTraitRef` rather than storing it on the side
Arguably we could move these modifiers into `TraitRef` instead of `PolyTraitRef`, but I see `TraitRef` as simply the *path* part of the trait ref. It doesn't really matter -- refactoring this further is much easier now.
ensure that a macOS os_unfair_lock that is moved while being held is not implicitly unlocked
Fixes https://github.com/rust-lang/miri/issues/3859
We mark an os_unfair_lock that is moved while being held as "poisoned", which means it is not considered forever locked. That's not quite what the real implementation does, but allowing arbitrary moves-while-locked would likely expose a ton of implementation details, so hopefully this is good enough.
`utcnow()` is deprecated in favor of passing a timezone to `now()`. `utcnow()` would return a tz-naive datetime, while this returns a tz-aware datetime. For the purposes of the formatting we do, these are the same.
