  -----------
  [X86] Align i128 to 16 bytes in x86 datalayouts

This is an attempt at rebooting https://reviews.llvm.org/D28990

I've included AutoUpgrade changes to modify the data layout to satisfy the compatible layout check. But this does mean alloca, loads, stores, etc in old IR will automatically get this new alignment.

This should fix PR46320.
