Hi all,

could you please review this patch which fixes type of tests? the fix is basically 's/TEST/TEST_VM/‘.

there are several tests which depend on initialized JVM, but do not declare it (by using TEST_VM macros). here is the list of those tests along w/ observations where/when they need JVM:
 
1. all arrayOopDesc tests use arrayOopDesc::header_size_in_bytes which depends on a jvm state, it reads HeapWordSize and UseCompressedClassPointers and furthermore has an assert which checks that their values haven't changed. 
2. all utilities/json tests use tty variable (as JSON::_st field), tty initialization is a port of jvm initialization. 
3. SymbolTable.temp_new_symbol calls JavaThread::current() 
4. LogFileOutput tests use ResourceMark which calls JavaThread::current() 
5. LogDecorations.level, uptime, tags and timestamps tests directly or indirectly call os::javaTimeNanos() which assumes that some structures, e.g. Bsd::_timebase_info, are inited 
6. LogConfigurationTest tests require ResourceMark or os::javaTimeNanos
