* ld-linkonce/x.s: Use .gcc_except_table instead of .eh_frame 

to test that entry for deleted function is zeroed.  Add a
	somewhat closer to normal .eh_frame to test that fde for
	deleted function is removed.
	* ld-linkonce/y.s: Likewise.
	* ld-linkonce/zeroeh.ld: Place .gcc_except_table too.
	* ld-linkonce/zeroehl32.d: Update.
