[PATCH] testsuite/92177 fix for SLP build changes

[Richard Biener]

We're now consistently building SLP operations with only
scalar defs from scalars which makes the testcase no longer
testing multiplication vectorization.  The following smuggles
in a constant making the vector variant profitable for SLP build.

Tested on x86_64-linux, pushed.

	PR testsuite/92177
	* gcc.dg/vect/bb-slp-22.c: Adjust.
