ZapUnusedHeapArea

[Bengt Rutisson]

Hi Tom,

I am all for making this a product flag. I just had a quick look at the 
webrev. I think there are two #ifndef ASSERT statements in 
MutableNUMASpace::ensure_parsability() that also should be removed.

Otherwise it looks good.

I implemented it while debugging what turned out to be a card marking issue in the compiler but I figured I'd ask before blowing it away.  The webrev is at http://cr.openjdk.java.net/~never/zapunused.  It's a moderately useful flag when debugging stale oop issues with the compiler since it causes you to die pretty much at the first use of the stale pointer.
