Specialize String#byteslice(a, b) (#9939)
* Specialize String#byteslice(a, b)
This adds a specialization for String#byteslice when there are two
parameters.
This makes our protobuf parser go from 5.84x slower to 5.33x slower
```
Comparison:
decode upstream (53738 bytes): 7228.5 i/s
decode protobuff (53738 bytes): 1236.8 i/s - 5.84x slower
Comparison:
decode upstream (53738 bytes): 7024.8 i/s
decode protobuff (53738 bytes): 1318.5 i/s - 5.33x slower
```
* Update yjit/src/codegen.rs
