Author: aggarwa4

New Revision: 128667

URL: http://llvm.org/viewvc/llvm-project?rev=128667&view=rev
Log:
Pass to infer types of load/store instructions. 
To be used by the dynamic type tracking insertion pass.

TODO: expand to ignore loads/stores only used for
copying values, as seen in the case of mrv.
