sqlite is huge at -O3
Bug 407794 made the optimization settings in the sqlite makefile actually take effect on mac and linux. There seems to be a tiny Ts win on mac and linux, but it doesn't show up on Talos.

So are we saying we don't want it to be huge and would rather take the perf hit, or what?
We don't know that -O3 is a perf win. We do know that it is larger.
So, a little more research shows that it is ~200k bigger at -O3 than -O2, and none of our metrics show a perf hit at -O2. The Ts win looks like it was from building spidermonkey at -Os, one of the other simultaneous changes we made.
drh tells me that we get a small win by compiling with -O3, but there's a small perf loss and a much smaller binary size with -Os. We might want to look into making that switch.
We seem to be building with -O2 anyway, so this looks like it's WORKSFORME
