Patch: FYI: gcj ICE fixlet

[Tom Tromey]

I'm checking this in as obvious on the trunk.

My earlier deprecation fix introduced an ICE.  If the user's code has
a bug, in one situation we can have `decl == NULL_TREE'; this causes
the deprecation check to crash.  Other code in this same function
checks decl as well, hence this patch.

	* parse.y (jdep_resolve_class): Only check deprecation if we found
	a decl.
