        Description

        This issue is to port a number of improvements to JVMCI from jvmci-8:

        * Move C++ state and functionality associated with a HotSpotJVMCIRuntime Java object into its peer JVMCIRuntime C++ object (e.g., the _shared_library_javavm moves from being a static field in JVMCIEnv to an instance field in JVMCIRuntime).
        * The management of JNI globals handles and Metadata handles passed to JVMCI Java code should also be moved to JVMCIRuntime.
        * Introduce tracing of low frequency JVMCIRuntime lifetime events (e.g. JVMCIRuntime lifetime phase events) at less verbose trace level.
        * Trace high frequency JVMCI events (e.g. CompilerToVM calls) at more verbose trace level.
        * Detect unsupported jvmci.* system properties and use fuzzy matching for an error message suggesting closely matching supported properties.
        * Improve javadoc for HotSpotJVMCIRuntime.attachCurrentThread.
        * Reduce calls to JavaThread::current() in conjunction with JNIAccessMark.
