These variables were later being eliminated by the dead-code-elimination pass, so you can't see them directly in the final output, but removing them affects the name mangling off all future symbols, so it causes an enormous ripple effect in the diff. And of course, it's a waste of time and memory to synthesize IRNodes just to destroy them later. If we disable control-flow analysis, we lose the dead-code-elimination pass entirely; this change is also beneficial for emitting better code when optimizations are turned off.
