Cetus Alias Analysis

[akshay9594]

The Alias analysis pass fails to analyze certain complex pointer declarations such as -
(int ( * )[NONZER+1])(void*)acol
Here "acol" is a 2D array and has global scope. Cetus makes a conservative decision and assumes every variable is aliased to every other variable. In such a scenario, passes like the privatization pass which depends on alias analysis fail to run to completion.
