The INCLUDE-FILE option is only used in the toolchain tests for now. If specified in a file test, the given file path is added to the test's arguments. For toolchain tests this makes the file's package available to the test. The `--custom-core` command line flag is added to the driver, which avoids adding the production `Core` package to the command line. Together, these allow a test to provide their own minimal `Core` package. For example, this would replace `Core` with the package and prelude in `facet_types.carbon`. ``` // INCLUDE-FILE: toolchain/testing/min_prelude/facet_types.carbon // EXTRA-ARGS: --custom-core ``` To support this: * //testing knows how to parse INCLUDE-FILE out of the header of a test file. * //testing adds the file to the virtual file system, and includes it in the test's arguments. * //toolchain/driver grows the --custom-core command line flag to avoid loading the production `Core` package. Tests that were creating their own minimal prelude to define BitAnd on types are now pointed to toolchain/testing/min_prelude/facet_types.carbon as the prelude. They no longer need to `import Core` in each test as a result. Such tests are no longer `no_prelude`, but instead have their own prelude. So they are moved to a `min_prelude` subdirectory.
