More stage1 test coverage

Great work. You mind doing one last rebase and then I'll mark this as auto-merge?

[wooster0]

I'm pretty sure I didn't change anything that would cause this new failure that previously didn't happen:

zig build-exe maximum_sized_integer_literal Debug x86_64-windows: error: thread 229607 panic: Segmentation fault at address 0xffff37fc3934

Pretty sure all I did was resolve the conflict and rebase on master/the InternPool changes.
Might be a regression. I added a if (builtin.os.tag == .windows) return; to test/cases/maximum_sized_integer_literal.zig for now.

[andrewrk]

Hmm, I did not take as close a look at the new test cases last time as I should have.

Please use panics instead of illegal behavior (i.e. assert) so that the tests are meaningful in safety-off optimization modes as well.

Also please use behavior tests where possible instead of run test cases.

[wooster0]

Oh, that is very true. I must've just taken that idea from other tests without thinking about it enough.

It's also very good to know that behavior tests are in fact preferable.

Interesting. This has also not previously happened before the rebase.

Anyway, AFAIU the zig downloads are broken right now so I'm going to wait till I can get the latest master from the download page.

[wooster0]

I'm going to try limiting tests that I think might have to do with the failure to linux-x86_64 for now.

Vectors are a likely culprit: #13782

[wooster0]

Thanks! That helps a lot.
