Is this for testing or "real mining"?
Because the internal miner was removed since: v0.13.0 (release note: https://bitcoin.org/en/release/v0.13.0#removal-of-internal-miner).
Although there's a RPC call for testing purposes and reasons written in the link.

Code? it's still in github: https://github.com/bitcoin/bitcoin/blob/master/src/miner.cpp | miner.h.
