testsuite: Generalise tree-ssa/shifts-3.c regexp

My recent gcc.dg/tree-ssa/shifts-3.c test failed on arm-linux-gnu
because it used widen_mult_expr to do a multiplication on chars.
This patch generalises the regexp in the same way as for f3.

gcc/testsuite/
	* gcc.dg/tree-ssa/shifts-3.c: Accept widen_mult for f2 too.
