We give the optimized code another chance on soft deopts in TurboProp.
If the deopt is happening on infrequently taken paths, then this will
let us reuse the optimized code for the subsequent executions. If the
soft deopts are happening multiple times on the same code, then we would
discard the optimized code. The number of deopts we would wait is
controlled by FLAG_reuse_opt_code_count.
