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:

在 CPython 3.15 或 main 分支上使用 wcmatch 測試套件重現該失敗，然後檢查 tests/test_globmatch.py::TestGlobMatchSpecial::test_empty_pattern_lists 和 wcmatch/_wcparse.py:338。空 pattern 清單測試和完整測試套件執行均不再出現 AttributeError 或相關的 JIT 損壞時，即表示完成。
