- Adds an empty prelude.carbon file - Imports that file in any non-Core package file - Adds --disable-prelude-import to avoid that - Adds --exclude-dump-file-prefix to be able to hide files from dumping - Used to hide core files (we can't do this by package name due to lex dumps, for example) - Restructures some tests to not rely on `i32`, particularly `alias` tests (which rely on a name ref) and tests with no prelude. I'm adding the framework for switching i32 to calling Int32 in the prelude, but I'm running into a separate error actually switching over. So that *mostly* works, but isn't quite ready for prime time. However, maybe the current state of this PR is still useful to review since it does a lot of the infrastructure work and adds the %Core everywhere?
