1. Fix the macros in IncludeFile.h to put everything in the llvm namespace 2. Replace the previous explicit mechanism in all the .h and .cpp files with the macros in IncludeFile.h This gets us a consistent mechanism throughout LLVM for ensuring linkage. Next step is to make sure its used in enough places. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28715 91177308-0d34-0410-b5e6-96231b3b80d8
