Structural pattern matching in `lit.cfg.py`

[0x12CC]

Describe the bug

#16016 added this line to our lit.cfg.py:

llvm/sycl/test-e2e/lit.cfg.py

Line 41 in 77abc08

match lit_config.params.get("test-mode", "full"):

Pattern matching requires Python 3.10 but our testing requirements page states that we need Python 3.8: https://github.com/intel/llvm/blob/sycl/llvm/docs/TestingGuide.rst#requirements. This causes Python errors when running tests on a system with Python 3.8 or 3.9.

To reproduce

Run the following command on a system with Python 3.8:

ninja check-sycl-e2e

Environment

• OS: Linux
