Detailed Description

FunctionPass class - This class is used to implement most global optimizations. Optimizations should subclass this class if they meet the following constraints:

1. Optimizations are organized globally, i.e., a function at a time
2. Optimizing a function does not cause the addition or removal of any functions in the module
