Do not rely on std::sort and std::erase to get list of unique
...
exit blocks. The output is dependent on addresses of basic block.
Add and use Loop::getUniqueExitBlocks.

Make Loop::getExitBlocks significantly faster for large loops. Instead of
...
pounding on Loop::contains (which is O(n) in the size of the loop), use a
sorted vector, which is O(log(N)) for each query. This speeds up Duraid's
horrible testcase from ~72s to ~31s in a debug build.

For PR780:
...
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.
