Patch: FYI: resolve.cc exception improvement

[Tom Tromey]

I'm checking this in on the trunk.  It is from Gary Benson.

This puts information about the inaccessible field or method into the
IllegalAccessError that is thrown during resolution.  This makes it
easier to figure out what is going wrong without resorting to gdb.

	* resolve.cc (_Jv_ResolvePoolEntry): Put field name in exception.
	(_Jv_SearchMethodInClass): Likewise.
