Re-enable marking functions for optimized compilation on the next call
when using OSR. We would previously do this for all functions. However,
it only benefits functions marked for concurrent recompilation. These
would potentially run unoptimized again and be OSRed again.
In addition any function that already was optimized concurrently had
it's optimized code removed and would have been recompiled. Functions to
be baselined would skip that and possibly deopt.
