[SLP] Do not skip tiny trees with gathered loads to vectorize
The isTreeTinyAndNotFullyVectorizable check for 2-node trees
(insertelement root + gather child) was too aggressive: it rejected
trees even when LoadEntriesToVectorize was non-empty, preventing
gathered loads from being vectorized into masked loads/strided loads, etc.
