Luke Lau 6d88343662 [IA] Add support for [de]interleave{4,6,8} (#141512) ...

This teaches the interleaved access pass to the lower the intrinsics for
factors 4,6 and 8 added in #139893 to target intrinsics.

Because factors 4 and 8 could either have been recursively
[de]interleaved or have just been a single intrinsic, we need to check
that it's the former it before reshuffling around the values via
interleaveLeafValues.

After this patch, we can teach the loop vectorizer to emit a single
interleave intrinsic for factors 2 through to 8, and then we can remove
the recursive interleaving matching in interleaved access pass.
