Consider implementing a C1 clone intrinsic that uses ArrayCopyNode for primitive arrays

C1 has an intrinsic for System.arraycopy. It might be beneficial and straightforward to wire up Object.clone to use the same ArrayCopyNode when applicable (primitive arrays, in particular):

osx-aarch64, -XX:TieredStopAtLevel=1
Benchmark (size) Mode Cnt Score Error Units
ArrayClone.byteArraycopy 15 avgt 15 3,729 ± 0,045 ns/op
ArrayClone.byteClone 15 avgt 15 76,019 ± 1,431 ns/op
ArrayClone.intArraycopy 15 avgt 15 5,269 ± 0,018 ns/op
ArrayClone.intClone 15 avgt 15 77,157 ± 1,203 ns/op

linux-x64, -XX:TieredStopAtLevel=1:
Benchmark (size) Mode Cnt Score Error Units
ArrayClone.byteArraycopy 15 avgt 15 9.888 ± 0.380 ns/op
ArrayClone.byteClone 15 avgt 15 81.546 ± 1.772 ns/op
ArrayClone.intArraycopy 15 avgt 15 15.783 ± 0.625 ns/op
ArrayClone.intClone 15 avgt 15 82.882 ± 2.447 ns/op

This was missed when initially adding a microbenchmark to compare System.arraycopy and array.clone during JDK-8302315
