Sanjay Patel	e5a32d720e	[InstCombine] move extend after insertelement if both operands are extended ... I was wondering how instcombine does on the examples in D109236, and we're missing a basic transform: inselt (ext X), (ext Y), Index --> ext (inselt X, Y, Index) https://alive2.llvm.org/ce/z/z2aBu9 Note that there are several possible extensions of this fold (see TODO comments).
