8242490: Upgrade to gcc 9.2 on Linux

[kevinrushforth]

This is a compiler upgrade on Linux from the current gcc 8.3 compiler to gcc 9.2. This will match a recent upgrade done for JDK 15 -- see JDK-8241721.

On a related note, using the gcc 9 compiler produces many (harmless) warnings that will be addressed by JDK-8241476 -- see PR #150.

I have run a full build and test using this new compiler.

I won't integrate this until Monday anyway. If you run into a problem with the actual builds using this compiler, let me know and I'll hold off further (it's been well-tested on my end).
