This appears to be a leftover from when these tests were first added in D62927. Because of this, these tests had never run with `check-asan` or `check-asan-dynamic`. I've tested locally that these tests do pass on both i686 MSVC and MinGW targets. They are disabled for 64-bit though, and I believe no LLVM buildbots are testing for 32-bit Windows targets.
