Tests using `logInfo` were taking an additional two seconds on my machine. This is a performance issue with the old code generator, where we spend all this time specializing the logging functions for `GoalM`. I have not checked whether the new code generator is also affected by this performance issue. Here is a small example that exposes the issue: ```lean import Lean set_option profiler true open Lean Meta Grind in def test (e : Expr): GoalM Unit := do logInfo e ``` cc @zwarich
