  -----------
  [CodeGen] Ensure relative vtables use llvm.type.checked.load.relative (#126785)

This intrinsic is used when whole program vtables is used in conjunction
with either CFI or virtual function elimination. The
`llvm.type.checked.load` is unconditionally used, but we need to use the
relative intrinsic for WPD and CFI to work correctly.
