Summary: Bulk zeroing reduction didn't work with G1, because arraycopy would call pre-barriers on uninitialized oops. The solution is to have version of arraycopy stubs that don't have pre-barriers. Also refactored arraycopy stubs generation on SPARC to be more readable and reduced the number of stubs necessary in some cases.

Summary: Rearranged the pre-barrier placement in arraycopy stubs so that they are properly called in case of chained calls. Also refactored the code a little bit so that it looks uniform across the platforms and is more readable.
