  Do not remove empty basic blocks which have address taken. (#67740)

This PR replaces `isMachineBlockAddressTaken` by `hasAddressTaken` to
include blocks which have their IR address taken as well. These blocks
are also not removable since their predecessors' terminators do not
directly point to the block.
