tree-optimization/110460 - fend off vector types from vectorizer

Browse source 
The following makes fending off existing vector types from vectorization
also apply to word_mode vector types.  I've chosen to add a positive
list of allowed scalar types here for clarity.

	PR tree-optimization/110460
	* tree-vect-stmts.cc (get_related_vectype_for_scalar_type):
	Only allow integral, pointer and scalar float type scalar_type.
