[meta] cases where treesitter rejects code that rustc accepts

[matthiaskrgr]

There are a a bunch of more cases where rustc compiles a file whereas treesitter-rustc throws an error, indicating a parsing failure in treesitter-rust.

Since I deem filing all these issues separately is not worth my time, here is a list of interesting test files:

the files can be found inside the rustc repo @ 0038c021031ce9f1ec2329469c8d85d0e681ef8f

Tested tree-sitter version was 0038c021031ce9f1ec2329469c8d85d0e681ef8f with a patched version of tree-sitter-rust 04352146022062c101b8ddd853adf17eadd8cf56 , as just adding both -git deps to a crate did not work out for me.
