I ran into an issue in an upcoming CL which generated a particularly ugly switch statement: switch (x) { default: discard;} So I cleaned this up, and while resolving this issue, managed to improve a bunch of existing codegen as well. The formatting change has been split out to a separate CL since it impacts so many golden outputs.
