RFR: 8294245: Make Compile::print_inlining_stream stack allocated [v3]

[Johan Sjölen]

> Hi,
> 
> Could I have  a review for this? It simplifies some auxiliary code in the Compile class related to its usage of stringStream. The only notable disadvantage is that Compile will take up `sizeof(stringStream) - sizeof(stringStream*)` more space on the stack.
> 
> Currently testing tier1-3 for this change, no errors yet and almost finished.
> 
> Thanks,
> Johan
