Matt added a comment to D119285: [SVE] Bail out of constructDup(...) optimization for fixed width vectors > 128 bits.

Thank you, Cameron (not a noise at all from my perspective--it's actually helped me in a related issue I've encountered)!

Matt added a comment to D119252: [AArch64][SVE] Fix selection failure during lowering of shuffle_vector.

FWIW, I can confirm the presence of ICE using the test case from https://reviews.llvm.org/D119285, https://llvm.godbolt.org/z/f1r6he545, as well as that this patch fixes the issue; thank you!
