tree-optimization/116081 - typedef vs. non-typedef in vectorization

The following addresses a behavioral difference in vector type
analysis for typedef vs. non-typedef.  It doesn't fix the issue
at hand but avoids a spurious difference in the dumps.

	PR tree-optimization/116081
	* tree-vect-stmts.cc (vect_get_vector_types_for_stmt):
	Properly compare types.
