re PR testsuite/91419 (gcc.dg/tree-ssa/pr91091-2.c, ssa-fre-61.c, ssa-fre-61.c with r273232)

2019-08-14  Richard Biener  <rguenther@suse.de>

	PR testsuite/91419
	* lib/target-supports.exp (natural_alignment_32): Amend target
	list based on BIGGEST_ALIGNMENT.
	(natural_alignment_64): Targets not natural_alignment_32 cannot
	be natural_alignment_64.
	* gcc.dg/tree-ssa/pr91091-2.c: XFAIL for !natural_alignment_32.
	* gcc.dg/tree-ssa/ssa-fre-77.c: Likewise.
	* gcc.dg/tree-ssa/ssa-fre-61.c: Require natural_alignment_32.
