Fri Jun 12 11:31:24 1998  Per Bothner  <bothner@cygnus.com>

	We used to have three different representations of the constant pool:
	the CPool structure, the tree_constant_pool, and the constructures
	used to build the Class object (which may need class and string
	constants) in compiled code.  None were appropriate for compiling
	to .class files, so I did a major overhaul.

	First, the tree_constant_pool array was removed.  Things were
	modified to the CPool structure in the JCF could be used.
	Second, a "capacity" field was added to the CPool, and functions
	written to search for a matching constant, adding one if not found.
	The code that generated the Class object was changed to use a CPool.
	The actual TREE_LISTs used to build the CONSTRUCTORs used for
	the static Class object are now only in build_constants_constructor.
	Finally, I wrote code which can generate a .class file (including its
	constant pool) from the RECORD_TYPE of a class.  This is a big step
	on the way to compiling Java source into .class files.
