[msan] Better use-after-free reports.
By attaching an extra integer tag to heap origins, we are able
to distinguish between uninits
- created by heap allocation,
- created by heap deallocation (i.e. use-after-free),
- created by __msan_allocated_memory call,
- etc.
See https://code.google.com/p/memory-sanitizer/issues/detail?id=35.
