void AnalysisUsage::setPreservesCFG ( )

setPreservesCFG - This function should be called by the pass, iff they do not:

1. Add or remove basic blocks from the function 2. Modify terminator instructions in any way.

This function annotates the AnalysisUsage info object to say that analyses that only depend on the CFG are preserved by this pass.
