There are a bunch of tasks that are running on the Enterprise RHEL 6.2 variant but not the ASan variant.

I believe we should run as many tasks as possible on the ASan variant to catch subtle leaks and memory errors. For example, adding the multiversion suite to the variant could help us detect issues in version compatibility code.

Missing tasks that could potentially be added:

1. aggregation_WT_ese
2. aggregation_read_concern_majority_passthrough_WT
3. dur_jscore_passthrough
4. jsCore_WT_ese
5. jsCore_minimum_batch_size_WT
6. jsCore_op_query
7. jsCore_op_query_WT
8. multiversion
9. read_concern_majority_passthrough_WT
10. replicasets_WT_ese
11. replicasets_legacy
12. sharded_collections_jscore_passthrough
13. sharded_collections_jscore_passthrough_WT
14. sharding_WT_ese
15. sharding_legacy
16. sharding_legacy_op_query_WT
17. sharding_op_query_WT

Ones we can't add:

1. lint (not necessary to lint with ASan)
2. jstestfuzz* ones (we need to clean up verify() failures first)
3. rlp* ones (we only test RLP on RHEL)
4. push
