LLVM already has a plug-in framework for loading new analysis and 
optimization passes (http://llvm.org/docs/WritingAnLLVMPass.html).  What 
makes your proposal different?

Doxygen docs are already available for LLVM (http://llvm.org/doxygen).  
Personally, I don't see a need to make them part of the Programmer's 
Manual, although having a link from the Programmer's Manual to the 
doxygen docs is probably a good idea (if it doesn't exist already).

The superoptimizer idea looks kinda cool.
