Hi Everyone,

Can I have a volunteer to review the changes, which were contributed by 
Brandon Mitchell at Twitter, for this CR? The webrev can be found at: 

When Tony removed the zero filling thread, the is_zeroed parameter in 
the HeapRegion constructor became unused. These changes remove that 
unused parameter and clean up the HeapRegion initialization code.

(x86 and sparc) and jprt (JohnC)
