[Lldb-commits] [lldb] [LLDB] Remove C++ language runtime dependency of Clang expression parser (PR #185450)

[via lldb-commits]

>From https://github.com/llvm/llvm-project/pull/169225#issuecomment-4024377289: There was a dependency cycle involving the C++ language runtime:
```
  //lldb/source/Plugins/TypeSystem/Clang:Clang ->
  //lldb/source/Plugins/ExpressionParser/Clang:Clang ->
  //lldb/source/Plugins/LanguageRuntime/CPlusPlus:CPlusPlus ->
  //lldb/source/Plugins/TypeSystem/Clang:Clang
```

`ExpressionParserClang` doesn't need to depend on the C++ language runtime. It only included a file, but didn't use it. This PR removes that dependency.
