1. have to be sure we're not talking about the assembler for llvm IR here, 
which is a totally different thing...I think we call clang.

2. bootstrapping. the stock toolchain on many systems can't build llvm 7.0, but 
also you don't want to be stuck with llvm-3.4's clang forever as the assembler 
on those systems either either.

The current system already would be better than that.
