Fix gcc.dg/tree-ssa/copy-headers-9.c and gcc.dg/tree-ssa/dce-1.c failures

[Jan Hubicka]

Hi,
this patch fixes template in the two testcases so it matches the output
correctly.  I did not re-test after last changes in the previous patch,
sorry for that.

gcc/testsuite/ChangeLog:

	* gcc.dg/tree-ssa/copy-headers-9.c: Fix template for tree-ssa-loop-ch.cc changes.
	* gcc.dg/tree-ssa/dce-1.c: Likewise.
