c2f97c59 - [SLP] Do not skip tiny trees with gathered loads to vectorize

[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. Reviewers: hiraditya, RKSimon Pull Request: https://github.com/llvm/llvm-project/pull/190181
