[compiler] Avoid spamming --trace-opt with lookup failures.

[compiler] Avoid spamming --trace-opt with lookup failures.

This stops printing a log line for when a lookup in the optimized code
map did not yield a result. Logging such a negative result that will
inevitably trigger a compile anyways has little benefit and just spams
the console unnecessarily.

LGTM.

Could have moved the output behind FLAG_trace_opt_verbose instead, but dropping
it entirely is fine too: it's not hard to add it back if someone wants to debug
the optimized code map.
