Dan Gohman adf28177eb [WebAssembly] Enhanced register stackification ...

This patch revamps the RegStackifier pass with a new tree traversal mechanism,
enabling three major new features:

 - Stackification of values with multiple uses, using the result value of set_local
 - More aggressive stackification of instructions with side effects
 - Reordering operands in commutative instructions to enable more stackification.
