Primitive types 1.4 updates

[Mark Wielaard]

Hi,

The following patch adds new 1.4 functionality to the Boolean, Double
and Float classes. It also makes Boolean a little bit more efficient
by always returning the predefined TRUE or FALSE instances when
possible.

    * java/lang/Boolean.java (valueOf boolean): new 1.4 method
    (toString boolean): idem
    (valueOf String): return one of the predefined Boolean instances
    * java/lang/Double.java (compare double double): new 1.4 method
    (compareTo Double): call new method
    * java/lang/Float.java (compare float float): new 1.4 method
    (compareTo Float): call new method

Is there any reason the primitive classes have not been merged with
libgcj? Some of those classes, like Boolean, are pure java. The only
difference seems to be the way they define the TYPE instance variable.
We use VMClassLoader.getPrimitiveClass("boolean") and libgcj seems to
use some compiler magic to set this field. Maybe we could just add a
VMClassLoader class to libgcj that does the magic?

Cheers,

Mark
