tree-optimization/106196 - properly update virtual SSA for vector stores

The following properly handles aggregate returns of the const marked
STORE_LANES internal function to update virtual SSA form on-the-fly
rather than relying on a costly virtual SSA rewrite.

	PR tree-optimization/106196
	* tree-vect-stmts.cc (vect_finish_stmt_generation): Properly
	handle aggregate returns of calls for VDEF updates.

	* gcc.dg/torture/pr106196.c: New testcase.
