8ee9065162 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

4428c3483b For PR950: 
This patch removes the SetCC instructions and replaces them with the ICmp
and FCmp instructions. The SetCondInst instruction has been removed and
been replaced with ICmpInst and FCmpInst.

a5bb9b49d3 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.

9781d44b6e 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.

a21497f1b8 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.

fab2186a2f Update isLCSSAForm to handle PHI nodes specially for live-out detection. This 
is the same as the recent patch to LCSSA.cpp.

on this.

560366562b 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.

2c6d390a60 Change from using a stub function to a stub variable for passing to the 
IncludeFile hack to ensure linkage of analysis passes. This works around
some -pedantic warnings about assigning an object to a function.
