JIT corruption in `wcmatch` test suite: `yield from []` triggers "AttributeError: 'list' object has no attribute 'send'"

Bug report

Bug description:

When running wcmatch 15.0.1 complete test suite (doesn't happen with parts of it, or the older version), I'm seeing the following corruption:

Tái hiện lỗi với bộ kiểm thử wcmatch trên CPython 3.15 hoặc nhánh main, sau đó kiểm tra tests/test_globmatch.py::TestGlobMatchSpecial::test_empty_pattern_lists và wcmatch/_wcparse.py:338. Công việc được xem là hoàn tất khi bài kiểm thử danh sách pattern rỗng và toàn bộ bộ kiểm thử chạy mà không gặp AttributeError hoặc lỗi hỏng JIT liên quan.
