This PR addressed below issue:
When i try to log stmt input in InjectPrefetch Pass using AsText(stmt), i get below error

TVMError: Check failed: memo_buf_.count(buffer) > 0 (0 vs. 0) : 
Error during compile function

I've noticed this problem at the same time. My advice is to print the buffer information in the header, and use there unique name to reference them in the body of IR.
