Subject: [PATCH] [CostModel][X86] Improve cost estimation of insert_subvector
 shuffle patterns of legalized types

In cases where the base/sub vector type in an insert_subvector pattern legalize to the same width through splitting, we can assume that the shuffle becomes free as the legalized vectors will not overlap.

Note this isn't true if the vectors have been widened during legalization (e.g. v2f32 insertion into v4f32 would legalize to v4f32 into v4f32).

Noticed while working on adding processShuffleMasks handling for SK_PermuteTwoSrc.
