Patch: use an enum

[Tom Tromey <tromey AT cygnus dot com>]

I'm committing the appended patch.
It changes java-insns.h to use an enum instead of a bunch of const ints.
I think enums are nicer.

1999-09-14  Tom Tromey  <tromey@cygnus.com>

	* include/java-insns.h: Turned constants into an enum.  Added
	multiple-inclusion protection.
