please review the following patch:


The VM crashes in product or fails with an assert in debug if -Xint and -XX:+UseCompiler is set. 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.

The solution is to catch such an inconsistent flag combination, issue a warning and reset the flag.

Tested with regression test and RBT (running).
