Restructure to reduce MIR references

This CL eliminates most of the MIR references in the lower-level
code generator.  This allows a higher level of code sharing with
the MIR->LIR and GreenlandIR->LIR lowering passes.

The invoke, launchpads and new array support will need some more
extensive refactoring (future CL).
