[PATCH] D29677: [buildbot] Add check-fuzzer to Asan buildbot on Windows.

[Marcos Pividori via Phabricator via llvm-commits]

mpividori updated this revision to Diff 87535.
mpividori added a comment.

+ Split build and testing into 2 steps so it is easier to understand when it fails.
+ Add asan dll path to `Path`, so it is found when executing the tests.
+ Add bin dir to `Path`, so tools like `FileCheck`, `not` and `sancov` are found when executing the tests.
