Hmm, I don't quite get it: shouldn't static linking actually increase the
binaries (and thus the package) size?

That 1G looks like a big jump from 259M of llvm39-3.9.1_1.txz to me.
I'm surely looking forward modularization of LLVM port; rebuilding it
every time becomes a real PITA given that X11 stack requires it. :-(
