[DOXYGEN] Searchability


Doxygen can generate an embedded search engine. This would help much in navigating the huge LLVM and CLANG source base.

Any objections to enable the generation by default? Or should this rather be an option in CMAKE? Or has it drawbacks that I do not see?

Probably disabled due to the extra build time? I want to see this happen too, though


Can you add an option to do this in CMAKE and then it can be evaluated if it should be turned on by default? If you let me know, I can try this out on the LLVM website when you have added the option.
