Original change's description:
> [regexp] Eagerly tier-up for very long strings
>
> For very long subject strings, the regexp interpreter is currently much slower
> than the native machine code execution. This CL implements eager tier-up to the
> compiler to avoid the performance penalty for subject strings of length greater
> than 1000.
