This CL adds three metrics for lazy compilation: the number of functions
compiled lazily, the total time spent on compiling functions lazily,
and the maximum time spent on compiling a single function. All three
metrics get recorded twice, once 5 seconds after instantiation, and once
20 seconds after instantiation.
