LGTM, thanks.

> 2. Specified triple as "mips-linux-gnu"; note: I don't think we can just specify an arch here because that won't initialize the target machine for 'opt'.


It will but the way it does it is a bit weird in my opinion. It takes the default target triple and swaps the first component for the value of -march as long as llvm::Triple recognizes it. This can potentially lead to some odd triples like mips-pc-windows-msvc but they work in many parts of LLVM.
