Statistic
The statistic reports requested of the compiler:
L2Operations ~ The most time-intensive level-two operations
DynamicLookups ~ The most time-intensive dynamic method lookups.
Primitives ~ The primitives that are the most time-intensive to run overall.
PrimitiveReturnTypeChecks ~ The primitives that take the most time checking return types.
NonprimitiveReturnTypeChecks ~ Returns from non-primitives that had to check the return type.

Non-primitive Return Type Checks report, organized by the raw function being returned into. This collects contextual timings for non-primitive returns that had to check the type of the return result.
