RFR: 8166002: Emulate client build on platforms with reduced virtual address space

[Vladimir Kozlov]

Add comment what the code does and why. Move the code into separate function reaturning bool. And condition CodeCache setting based on result. It will reduce #ifdef mess.

Can you put && to the end of previous line? To get good alignment.
Should we also change CompilationPolicyChoice?

Ask Igor Veresov to verify settings.

Thanks,
Vladimir
