[PATCH] middle-end/123175 - fix vec_perm_indices construction in selftests

The two mixed VLA / non-VLA tests happen to mix up the number of
element argument to vec_perm_indices construction.

Built/tested on x86_64-unknown-linux-gnu, pushed.

Richard.

	PR middle-end/123175
	* fold-const.cc (test_vnx4si_v4si): Fixup vec_perm_indices
	construction.
	(test_v4si_vnx4si): Likewise.
