Log message:
        PR44411: Make VMSystem.nanoTime independent of wall time where possible.

                Provide a fallback for systems without POSIX timers.
                * native/jni/java-lang/java_lang_VMSystem.c:
                (currentTimeMillis): New function which provides
                the behaviour for both Java_java_lang_VMSystem_currentTimeMillis
                and the fallback by obtaining the result of gettimeofday.
                (Java_java_lang_VMSystem_nanoTime): Return currentTimeMillis
                multiplied by a 1000 if a monotonic clock is unavailable.
                (Java_java_lang_VMSystem_currentTimeMillis): Split main 
behaviour
                out into currentTimeMillis and then return its result divided 
by a
                1000.

                PR classpath/44411
                * native/jni/java-lang/java_lang_VMSystem.c:
                (Java_java_lang_VMSystem_nanoTime): Implement
                using POSIX monotonic clock support and clock_gettime.
                (Java_java_lang_VMSystem_currentTimeMillis):
                Use old nanoTime method (which uses gettimeofday) to
                provide the current time in milliseconds.
                * vm/reference/java/lang/VMSystem.java:
                (currentTimeMillis()): Make native with its own implementation
                rather than using nanoTime, which should be
                independent of wall-clock time.
