Add sanitizers

[pwang7]

Rust supports several sanitizers:

• AddressSanitizer a fast memory error detector.
• LeakSanitizer a run-time memory leak detector.
• MemorySanitizer a detector of uninitialized reads.
• ThreadSanitizer a fast data race detector.

Note that each sanitizer supports different architecture, and only a single sanitizer can be enabled at a time.
