RFR (S) : 8014362 : Need to expose some processor features via Unsafe interface

[David Chase]

There was a spacing change that did not get reverted.
This time, for sure.
Note that this sets a property that won't get reset without a companion change in the JDK.
(And the companion change is getting a bit of a pushback, though I hope to find, once I digest
all the benchmarks I ran this afternoon, that it's not as scary as feared.)
