Fix the bug of assignment conversion: 'short s = 12' should be allowed. And for such case, in BuildFlat.java the right side of the assignment is replaced with the value.

The second to last check in for the refactoring process. This moved/renamed some things to make the code more obvious. The last checkin will eliminate the need to coalesce connected heap groups.
