  |     [InstCombine] Canonicalize constant GEPs to i8 source element type (#68882)
  |     
  |     This patch canonicalizes getelementptr instructions with constant
  |     indices to use the `i8` source element type. This makes it easier for
  |     optimizations to recognize that two GEPs are identical, because they
  |     don't need to see past many different ways to express the same offset.

This one is the new warning tied to the above LLVM change, I filed
https://github.com/ClangBuiltLinux/linux/issues/1985 for that a little
bit ago.

This one is https://github.com/ClangBuiltLinux/linux/issues/1966.
