It seems that 12ad4d41 enabled
collection by default as its needs stats.allocated_bytes to determine
whether the program has exceeded its grace limit.

However, enabling stats also enables some potentially expensive times
checks.  In general GC statistics should be cheap to compute (relative
to the GC itself), so now we always compute them. This allows us to once
again disable giveStats by default.

Fixes #13864.
