Several runtime/CommandLine fails with fastdebug bundles

Several runtime/CommandLine fails with fastdebug bundles, because processing of some options may be different comparing to product bundles.

Following tests are affected:
a) runtime/CommandLine/CompilerConfigFileWarning.java
runtime/CommandLine/ConfigFileWarning.java

Root cause: fastdebug JVM uses default compiler config and hotspot config files when appropriate CLI options are omitted.

b) runtime/CommandLine/VMOptionWarning.java

Root cause: UnlockUnreognizedVMOptions is true in debug, but test based on assumption that usage of diagnostic option w/o UnlockUnreognizedVMOptions will cause startup failure.

These tests should be updated to work correctly with both product and fastdebug builds.
