#[should_fail] unit tests are broken on windows

[crnobog]

Running the std unit tests on windows finishes with

running 1042 tests
test ascii::tests::test_ascii ... ok
test ascii::tests::test_ascii_fail_char_slice ... rust: task failed at '955 is not ascii', C:\code\rust\src\libstd\str\ascii.rs:143
rust: domain main @0xb93960 root task failed

Looks like the fail!() that is supposed to cause the test to pass is bringing down the whole executable instead of just the one test. May be related to #7999 .

This is just a symptom of #908. Any test case with #[should_fail] should also have #[ignore(cfg(windows))], so this is probably a bug in an individual test.

#908 was closed yesterday, so we should revisit should_fail tests like this.

This is no more problem (and should_fail tests are run on Windows now).
