Simplify CFG copying tables
This simplifies the maps between original and new basic blocks and
loops as used for CFG copying. Instead of using a pointer hash
table to allocated mapping entries use a hash_map with int_hash,
removing the indirection and code duplication. We can use -1 and
-2 as empty/deleted values as those are not valid basic-block
indices or loop numbers.
