Bug 470244 - Replace new Boolean with Boolean.valueOf

Using `new Boolean()` results in the creation of a new object on the
heap, when the flyweight `Boolean.TRUE` and `Boolean.FALSE` are available.
Java 1.4 added a `Boolean.valueOf()` which can be used in place of
`new Boolean()` but which will use the existing flyweight values instead.

Globally change `new Boolean(...)` to `Boolean.valueOf(...)` and replace
constant valued expressions with their flyweight counterparts.
