[CodeGen] Use optimized domtree for MachineFunction (#102107)
The dominator tree gained an optimization to use block numbers instead
of a DenseMap to store blocks. Given that machine basic blocks already
have numbers, expose these via appropriate GraphTraits. For debugging,
block number epochs are added to MachineFunction -- this greatly helps
in finding uses of block numbers after RenumberBlocks().
In a few cases where dominator trees are preserved across renumberings,
the dominator tree is updated to use the new numbers.
