Chris Lattner has strong opinions about directory
layout. :) Rename the 'EntoSA' directories to 'StaticAnalyzer'. Internally we will still use the 'ento' namespace for the analyzer engine (unless there are further sabre rattlings...). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122514 91177308-0d34-0410-b5e6-96231b3b80d8
