URL: https://github.com/llvm/llvm-project/commit/afb9883c70663f273a7a785100e3edf1b769d511 DIFF: https://github.com/llvm/llvm-project/commit/afb9883c70663f273a7a785100e3edf1b769d511.diff LOG: [clang] Pass VFS to driver's `ExpansionContext` (#173292) The `ExpansionContext` constructor calls `vfs::getRealFileSystem()` when not given VFS explicitly, leading to sandbox violations. This PR passes the VFS into the constructor instead of calling `setVFS()` later.
