Undefined references to rust_eh_unwind_resume on x86_64-pc-windows-gnu

[alexcrichton]

Originally from rust-lang/rust#43095 the reason this doesn't "just work" is because of rust-lang/rust#43151 and rust-lang/rust#43150. We should find a workaround in this repository for avoiding those bugs and check this into the test suite:

diff --git a/ci/run.sh b/ci/run.sh

One possible workaround may be to make these methods (I think the Int::aborting_* methods) generic with a random type parameter to force codegen to not generate landign pads here. Another "fix" would to actually fix these bugs upstream!

Both mentioned issues are closed and there is rust-lang/rust#70846
This issue shouldn't be the case anymore.

The eh_unwind_resume lang item was removed in #67502. This issue can be closed.
