4b8f36f106 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.

69b3992154 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.

880ddb018a Speed up Loop::isLCSSAForm by using a binary search and single-entry cache.
This reduces LCSSA pass time from 1.5s to 0.96s when run on eon in release+asserts mode.

3cc86cc11f Update isLCSSAForm to handle PHI nodes specially for live-out detection. This
is the same as the recent patch to LCSSA.cpp.

on this.

4f1bd9e996 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.

192913e281 Change from using a stub function to a stub variable for passing to the

some -pedantic warnings about assigning an object to a function.
