Some tests assumed that there would only be 2 vector sizes if
vect_multiple_sizes, whereas for SVE there are three (SVE, 128-bit
and 64-bit).  This patch replaces scan-tree-dump-times with
scan-tree-dump for vect_multiple_sizes but keeps it for
!vect_multiple_sizes.

	* gcc.dg/vect/no-vfa-vect-101.c: Use scan-tree-dump rather than
	scan-tree-dump-times for vect_multiple_sizes.
	* gcc.dg/vect/no-vfa-vect-102.c: Likewise.
	* gcc.dg/vect/no-vfa-vect-102a.c: Likewise.

	* gcc.dg/vect/no-vfa-vect-79.c: Likewise.
	* gcc.dg/vect/vect-104.c: Likewise.
