  When -march=cascadelake is added we get 256bit vectorization by
default but there's no OMP SIMD ABI for this case with inbranch.
So add -mprefer-vector-width=512 to the testcase.

Tested on x86_64-unknown-linux-gnu, pushed.

	PR tree-optimization/122776
	* gcc.dg/vect/vect-simd-clone-24.c: Add -mprefer-vector-width=512.
