AddressSanitizer reports errors for tests in llvm-test-suite

Current llvm-test-suite version triggers a number of ASan failures.

The issue was tested at the commit f3710ea5dcfdcef972f2cfd18e2733b7c83ca3f3 of llvm-test-suite, built with system-provided Clang 20 from Ubuntu 25.04 (x86_64) repository.

## How to reproduce

Checkout current version of llvm-test-suite from https://github.com/llvm/llvm-test-suite, create `cmake/caches/asan.cmake` file with the following contents:

```cmake
set(OPTFLAGS "${OPTFLAGS} -O1 -g -fsanitize=address -fno-omit-frame-pointer -fno-optimize-sibling-calls")

set(CMAKE_C_FLAGS_RELEASE "${OPTFLAGS}" CACHE STRING "")
set(CMAKE_CXX_FLAGS_RELEASE "${OPTFLAGS}" CACHE STRING "")
set(CMAKE_BUILD_TYPE "Release" CACHE STRING "")
```

disable `Bitcode/*` and `MicroBenchmarks/XRay/*` tests:

git diff

```
diff --git a/Bitcode/CMakeLists.txt b/Bitcode/CMakeLists.txt

+# add_subdirectory(XRay)

add_subdirectory(harris)

```

Then build and run the test suite with

```bash
$ mkdir build && cd build
$ CC=clang CXX=clang++ cmake -G Ninja .. -C ../cmake/caches/asan.cmake
$ ninja
$ ASAN_OPTIONS=detect_leaks=0 /path/to/bin/llvm-lit -va .
```

Note that LeakSanitizer is disabled, as otherwise its reports would make the output of test executables differ from the reference output.

## Expected results

No unexpected failures are reported (at least non-false-positives).

## Actual results

13 test failures are reported:

Start by reproducing the ASan configuration from cmake/caches/asan.cmake and running the provided CMake, Ninja, and llvm-lit commands. Then inspect the reported failures, including Versioning.cpp, d6-arith.cpp, decomp.cpp, and jcparam.c. Done means the suite reports no unexpected failures.

Written by the indexing model from the issue text.
