google search boxes for llvm site

Just a quick note: I added a search box to the main page, allowing an easy search of the whole llvm site, and a search box the to page, allowing a search of just the documentation.

Thanks to Tanya for suggesting this :slight_smile:


Ooh, ooh, feature request -- a search box for mailing list archives. :wink:

I considered doing that, but with a few simple tests it didn't seem to work very well. If you want to play around with it, feel free. :slight_smile:
