RFR: 8201494: Avoid early initialization of java.nio.Bits

[Claes Redestad]

Hi,

we initialize a couple of HeapByteBuffer during System.initPhase1 (due 
System.out/in), which right now pulls in java.nio.Bits and a few other 
dependent classes (AtomicLong...). This can be avoided by removing 
Bits.unsafe() and moving the read of native byte order from Bits to 
ByteOrder, which all in all seems like a nice cleanup.

Thanks!
