ChildLocalizer: Do not use locals needlessly (#4292)
We only need to use locals if there are effects we can't remove, or if they
interact with other children. Improve the comment to explain what the
ChildLocalizer is working towards: a state where all the children of the
expression can be reordered or removed freely (local.gets have that
property, as do other things if they have no relevant effects).
Aside from avoiding wasteful locals, this is necessary for running
GlobalTypeOptimization on j2wasm: That code will do a global.get
of an rtt, and those cannot be placed in locals.
