simd-3.c: (main): Change type of res and ref from int to double.

2015-07-14  Maxim Blumenthal  <maxim.blumenthal@intel.com>

libgomp/
	* testsuite/libgomp.c/examples-4/simd-3.c: (main): Change type of res
	and ref from int to double.  Replaced their comparison with
	an inequality of their difference and EPS.
	* testsuite/libgomp.c/examples-4/simd-8.c: (main): Replace the
	comparison of pri and a reference number with an inequality of their
	difference and EPS.
	* testsuite/libgomp.fortran/examples-4/simd-3.f90: (main): Replaced
	the comparison of sum and sum_ref with an inequality of their
	difference and EPS.
	* testsuite/libgomp.fortran/examples-4/simd-8.f90: (main): Replace
	the comparison of pri and a reference number with an inequality of
	their difference and EPS.
