As discussed in PR #142353, the current testsuite of the `clang` Python bindings has several issues: - It `libclang.so` cannot be loaded into `python` to run the testsuite, the whole `ninja check-all` aborts. - The result of running the testsuite isn't report like the `lit`-based tests, rendering them almost invisible. - The testsuite is disabled in a non-obvious way (`RUN_PYTHON_TESTS`) in `tests/CMakeLists.txt`, which again doesn't show up in the test results. All these issues can be avoided by integrating the Python bindings tests with `lit`, which is what this patch does: - The actual test lives in `clang/test/bindings/python/bindings.sh` and is run by `lit`. - The current `clang/bindings/python/tests` directory (minus the now-subperfluous `CMakeLists.txt`) is moved into the same directory. - The check if `libclang` is loadable (originally from PR #142353) is now handled via a new `lit` feature, `libclang-loadable`. - The various ways to disable the tests have been turned into `XFAIL`s as appropriate. This isn't complete and not completely tested yet. Tested on `sparc-sun-solaris2.11`, `sparcv9-sun-solaris2.11`, `i386-pc-solaris2.11`, `amd64-pc-solaris2.11`, `i686-pc-linux-gnu`, and `x86_64-pc-linux-gnu`.
