Title: Upgrade LLVM

This upgrade brings commit by @eddyb to help optimizations of virtual calls in
a few places (https://github.com/llvm-mirror/llvm/commit/6d2bd95) as well as a
commit by @c-a to *greatly* improve the runtime of the optimization passes
(https://github.com/rust-lang/llvm/pull/3).

Nice work to these guys!
