History
Mehdi Amini 7da0eff84e Update InstCombine to transform aggregate loads into scalar loads. 
Summary:
One step further getting aggregate loads and store being optimized
properly. This will only handle struct with one element at this point.

Test Plan: Added unit tests for the new supported cases.
