Nikita Popov ed76074173 [LICM] Remove custom isInstInList() implementation (PR59324) ...

We already collect all instructions that need to be promoted. The
custom isInstInList() implementation could provide incorrect
results if a new use of the original pointer was introduced as
part of promotion. This probably cannot happen with normal code,
because of the pointer capture, but it can happen with a null
pointer.

Fixes https://github.com/llvm/llvm-project/issues/59324.
