Due to current prototype limitation, we cannot yet store the generated code that has the expanded code buffer. I tried to address that directly, but I think relocations disagree with the whole thing, so this implementation limitation stays for a bit longer.

But we can dodge significant part of the hit by bumping the default code buffer sizes, and thus making buffers less likely to require resizing, and thus allowing to store more code in SCC.
