`RecursivelyDeleteTriviallyDeadInstructions` is introduced by
https://github.com/llvm/llvm-project/pull/149047 to immediately drop
dead instructions. However, it may invalidate the next iterator in
`make_early_inc_range` in some edge cases, which leads to a crash. This
patch manually maintains the next iterator and updates it when the next
instruction is about to be deleted.
Closes https://github.com/llvm/llvm-project/issues/155110.
