[X86] EltsFromConsecutiveLoads - support common source loads (REAPPLIED)

This patch enables us to find the source loads for each element, splitting them into a Load and ByteOffset, and attempts to recognise consecutive loads that are in fact from the same source load.

A helper function, findEltLoadSrc, recurses to find a LoadSDNode and determines the element's byte offset within it. When attempting to match consecutive loads, byte offsetted loads then attempt to matched against a previous load that has already been confirmed to be a consecutive match.

Next step towards PR16739 - after this we just need to account for shuffling/repeated elements to create a vector load + shuffle.

Fixed out of bounds load assert identified in rL366501
