Thomas Lively 5286180999 [WebAssembly] Fix RegStackify and ExplicitLocals to handle multivalue ...

Summary:
There is still room for improvement in the handling of multivalue
nodes in both passes, but the current algorithm is at least correct
and optimizes some simpler cases. In order to make future
optimizations of these passes easier and build confidence that the
current algorithms are correct, this CL also adds a script that
automatically and exhaustively generates interesting multivalue test
cases.
