tests: use minicore more

minicore makes it much easier to add new language items to all of the existing `no_core` tests.

Most of the remaining tests that *could* use minicore either fail because..

1. LLVM IR output changes and doesn't pass the test as written. I didn't look into these further.
2. The test has revisions w/ different compilation flags, expecting some to fail, and when using minicore, minicore is compiled with those flags and fails in the expected way because of the flags rather than the test, and that's considered a failure.

But these tests can be changed and make adding new language items a lot easier.
