[llvm] [IR] BlockAddress doesn't use BasicBlock (PR #200772)

Makes sense to me. Some time ago I dropped blockaddress from the Function use list, dropping it from the BB use list as well is consistent with that...

Regarding uselistorder_bb, note that we also have USELIST_CODE_BB in bitcode.

Is this actually redundant though? The docs only talk about blockaddress, but isn't the use list order for BBs also relevant because it determines the order of the predecessors iterator?
