[PATCH] D74976: [CostModel][X86] Improve extract/insert element costs (PR43605)

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon updated this revision to Diff 245932.
RKSimon added a comment.

Simplify extract cost - we only care about getting the element into the 0'th index (so not a full unary shuffle, something much cheaper).

Add AVX1/AVX2 interleaving target tests
