getAndSet not inlined for Java.util.concurrency.atomic.Atomiclong and AtomicLongArray

[matthewhall2]

On Z in J9CodeGenerator::inlineDirectCall, the atomics for getAndSet for AtomicLong and AtomicLongArray are not being inlined, even though they are being inlined for the integer versions (AtomicInteger and AtomicIntegerArray).

getAndSet for Long types appears to be covered in Z::J9TreeEvaluator::inlineAtomicOps, and are included J9RecognizedMethods.enum. It looks like it may have just been missed in J9CodeGenerator::inlineDirectCall
