[clang] SIGSEGV at DeduceTemplateArgumentsByTypeMatch
8eaa05d 
There is a SIGSEGV at `DeduceTemplateArgumentsByTypeMatch`. The bug [llvm#51171](https://bugs.llvm.org/show_bug.cgi?id=51171) was filled. The reproducer can be found at the bug description.

LIT test for the issue was added:
```
./bin/llvm-lit -v ../clang/test/SemaCXX/pr51171-crash.cpp
```

The debug stack trace is below:

[clangd] Print current request context along with the stack trace
045695f 
Motivation:

At the moment it is hard to attribute a clangd crash to a specific request out of all in-flight requests that might be processed concurrently. So before we can act on production clangd crashes, we have to do quite some digging through the log tables populated by our in-house VSCode extension or sometimes even directly reach out to the affected developer. Having all the details needed to reproduce a crash printed alongside its stack trace has a potential to save us quite some time, that could better be spent on fixing the actual problems.

Implementation approach:

* introduce `ThreadCrashReporter` class that allows to set a temporary signal handler for the current thread
* follow RAII pattern to simplify printing context for crashes occurring within a particular scope
* hold `std::function` as a handler to allow capturing context to print
* set local `ThreadCrashReporter` within `JSONTransport::loop()` to print request JSON for main thread crashes, and in `ASTWorker::run()` to print the file paths, arguments and contents for worker thread crashes

`ThreadCrashReporter` currently allows only one active handler per thread, but the approach can be extended to support stacked handlers printing context incrementally.

Example output for main thread crashes:

  ```
  ...
  rust-lang#15 0x00007f7ddc819493 __libc_start_main (/lib64/libc.so.6+0x23493)
  rust-lang#16 0x000000000249775e _start (/home/emmablink/local/llvm-project/build/bin/clangd+0x249775e)
  Signalled while processing message:
  {"jsonrpc": "2.0", "method": "textDocument/didOpen", "params": {"textDocument": {"uri": "file:///home/emmablink/test.cpp", "languageId": "cpp", "version": 1, "text": "template <typename>\nclass Bar {\n  Bar<int> *variables_to_modify;\n  foo() {\n    for (auto *c : *variables_to_modify)\n      delete c;\n  }\n};\n"}}}
  ```

Example output for AST worker crashes:

  ```
  ...
  rust-lang#41 0x00007fb18304c14a start_thread pthread_create.c:0:0
  rust-lang#42 0x00007fb181bfcdc3 clone (/lib64/libc.so.6+0xfcdc3)
  Signalled during AST action:
  Filename: test.cpp
  Directory: /home/emmablink
  Command Line: /usr/bin/clang -resource-dir=/data/users/emmablink/llvm-project/build/lib/clang/14.0.0 -- /home/emmablink/test.cpp
  Version: 1
  Contents:
  template <typename>
  class Bar {
    Bar<int> *variables_to_modify;
    foo() {
      for (auto *c : *variables_to_modify)
        delete c;
    }
  };
  ```

Testing:

The unit test covers the thread-localitity and nesting aspects of `ThreadCrashReporter`. There might be way to set up a lit-based integration test that would spawn clangd, send a message to it, signal it immediately and check the standard output, but this might be prone to raceconditions.

[lldb][TypeSystem] ForEach: Don't hold the TypeSystemMap lock across …
e74f03d 
…callback

The `TypeSystemMap::m_mutex` guards against concurrent modifications
of members of `TypeSystemMap`. In particular, `m_map`.

`TypeSystemMap::ForEach` iterates through the entire `m_map` calling
a user-specified callback for each entry. This is all done while
`m_mutex` is locked. However, there's nothing that guarantees that
the callback itself won't call back into `TypeSystemMap` APIs on the
same thread. This lead to double-locking `m_mutex`, which is undefined
behaviour. We've seen this cause a deadlock in the swift plugin with
following backtrace:

```

int main() {
    std::unique_ptr<int> up = std::make_unique<int>(5);

    volatile int val = *up;
    return val;
}

clang++ -std=c++2a -g -O1 main.cpp

./bin/lldb -o “br se -p return” -o run -o “v *up” -o “expr *up” -b
```

Our solution is to simply iterate over a local copy of `m_map`.

* Confirmed on manual reproducer (would reproduce 100% of the time

Revert "[Coro] [async] Disable inlining in async coroutine splitting (l…
2e29c91 
…lvm#80904)"

This reverts commit b1ac052.

This commit breaks coroutine splitting for non-swift calling convention
functions. In this example:

```ll
; ModuleID = 'repro.ll'
source_filename = "stdlib/test/runtime/test_llcl.mojo"
target datalayout = "e-m:e-p270:32:32-p271:32:32-p272:64:64-i64:64-i128:128-f80:128-n8:16:32:64-S128"
target triple = "x86_64-unknown-linux-gnu"

@0 = internal constant { i32, i32 } { i32 trunc (i64 sub (i64 ptrtoint (ptr @craSH to i64), i64 ptrtoint (ptr getelementptr inbounds ({ i32, i32 }, ptr @0, i32 0, i32 1) to i64)) to i32), i32 64 }

define dso_local void @af_suspend_fn(ptr %0, i64 %1, ptr %2) #0 {
  ret void
}

define dso_local void @craSH(ptr %0) #0 {
  %2 = call token @llvm.coro.id.async(i32 64, i32 8, i32 0, ptr @0)
  %3 = call ptr @llvm.coro.begin(token %2, ptr null)
  %4 = getelementptr inbounds { ptr, { ptr, ptr }, i64, { ptr, i1 }, i64, i64 }, ptr poison, i32 0, i32 0
  %5 = call ptr @llvm.coro.async.resume()
  store ptr %5, ptr %4, align 8
  %6 = call { ptr, ptr, ptr } (i32, ptr, ptr, ...) @llvm.coro.suspend.async.sl_p0p0p0s(i32 0, ptr %5, ptr @ctxt_proj_fn, ptr @af_suspend_fn, ptr poison, i64 -1, ptr poison)
  ret void
}

define dso_local ptr @ctxt_proj_fn(ptr %0) #0 {
  ret ptr %0
}

; Function Attrs: nomerge nounwind
declare { ptr, ptr, ptr } @llvm.coro.suspend.async.sl_p0p0p0s(i32, ptr, ptr, ...) #1

; Function Attrs: nounwind

attributes #0 = { "target-features"="+adx,+aes,+avx,+avx2,+bmi,+bmi2,+clflushopt,+clwb,+clzero,+crc32,+cx16,+cx8,+f16c,+fma,+fsgsbase,+fxsr,+invpcid,+lzcnt,+mmx,+movbe,+mwaitx,+pclmul,+pku,+popcnt,+prfchw,+rdpid,+rdpru,+rdrnd,+rdseed,+sahf,+sha,+sse,+sse2,+sse3,+sse4.1,+sse4.2,+sse4a,+ssse3,+vaes,+vpclmulqdq,+wbnoinvd,+x87,+xsave,+xsavec,+xsaveopt,+xsaves" }
attributes #1 = { nomerge nounwind }
attributes rust-lang#2 = { nounwind }
```

This verifier crashes after the `coro-split` pass with

```
cannot guarantee tail call due to mismatched parameter counts
  musttail call void @af_suspend_fn(ptr poison, i64 -1, ptr poison)
