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.
