Amend gcc.dg/vect/fast-math-vect-call-2.c

There was a reported regression on x86-64 with -march=cascadelake
and -m32 where epilogue vectorization causes a different number of
SLPed loops.  Fixed by disabling epilogue vectorization for the
testcase.

	* gcc.dg/vect/fast-math-vect-call-2.c: Disable epilogue
	vectorization.
