Patch: runtime support for `null this' patch

[Tom Tromey]

I'm checking this in.  It is the runtime part of my fix for PR 2.

2000-04-05  Tom Tromey  <tromey@cygnus.com>

	Runtime support for PR gcj/2:
	* prims.cc (_Jv_ThrowNullPointerException): New function.
	* include/jvm.h (_Jv_ThrowNullPointerException): Declare.
