[9] RFR(S): 8086068: VM crashes with "-Xint -XX:+UseCompiler" options

[Dmitry Dmitriev]

Hi Tobias,

Can comment only about new test: I think that you don't need @library 
and @modules for this simple test. Not need a new webrev for that. Thank 
you!

This is because CodeCache::heap_available() relies on the fact that if Arguments::mode() == _int, no compilation will be triggered. Although UseCompiler is first disabled by -Xint, the flag may be re-enabled if set via command line.
