Well, the official way to use LTO is with "-flto". -emit-llvm is more
of a debugging flag that just happens to send code through the LTO
path by coincidence.

Anyway, for disadvantages: LTO compiles will probably take longer and
use more memory (possibly lots). Problems could be harder to track
down. But it does give rather impressive speedups from what I've
heard.

Cheers.
