OpenJDK 12-dev fastdebug for X86: Native memory allocation (malloc) failed to allocate 3276800 bytes for CodeCache: no room for Interpreter

[Leslie Zhai]

Hi Erik,

I want to verify JDK-8199417 with OpenJDK 12-dev fastdebug for X86:

$ ./configure --with-debug-level=fastdebug 
--with-boot-jdk=/home/xiangzhai/jdk-10.0.2 --disable-warnings-as-errors

Then *deliberately* changed `InterpreterCodeSize` too big, for example 800K:

----- 8< -------- 8< -------- 8< -------- 8< -------- 8< -------- 8< ---

So there is the upper limit value for `InterpreterCodeSize`?  Is it able 
to workaround MIN(quadrupled, MAX_VALUE) for debug builds in order to 
accommodate for the additional debugging code?

Please give me some suggestions, thanks a lot!

Thanks,
