The test still fails, now with:
ERROR: gcc.dg/tree-ssa/flatten-3.c: syntax error in target selector "-fno-ipa-icf" for " dg-options 2 -O2 -fno-ipa-icf "

Fixed thusly, committed as obvious:

2017-01-11  Jakub Jelinek  <jakub@redhat.com>

	* gcc.dg/tree-ssa/flatten-3.c: Add quotation marks around dg-options
	argument.
