I think it's a great idea, and I'm sure I can find some things to add as well.
We've had to go in and read the source code to LLVM many times during
the development of LDC (the D compiler), and lots of this have been
fairly simple stuff, where a few notes in a wiki could have saved us
time. It all adds up.

Especially one feature of LLVM that's extremely underdocumented,
inline assembler, has been very important for LDC, which needs inline
asm as it is part of the language specification. I've tried writing a
document proposal before but I didn't really find the time, and there
was still a lot of things I didn't (and don't) know how worked, so it
never got done. I can easily imagining starting a small wiki page to
collect some reference information though.
