RFR: 8355711: Fix incorrect overflow check in RawBytecodeStream::raw_next [v3]

[Johan Sjölen]

> Hi,

> This fixes a typical wrong overflow check. `_bci` and `_next_bci` are both `int`, so any overflow is undefined, therefore an optimizing C++ compiler is allowed to remove this check. When looking at the x64 assembly for this, I could not find the check, so I guess that it was actually removed as well.
