carefully selecting VL so that we don't overwrite any more destination
elements than what we have to.

containing the operations produced by the PFT-to-MLIR lowering bridge, and
another at the end of the process, just before LLVM IR generation.

This is accomplished by forwarding the -save-temps flag from the driver to the
frontend, and modifying it to output MLIR files accordingly.
