Jonas Jensen a235d7aaff C++ IR: Reuse expensive IRBlock computations ...

`IRBlock` contains a few expensive predicates, mostly `getInstruction`
and `immediatelyDominates`. These were previously recomputed for each of
the three SSA layers even though they essentially produce the same
result in each layer. The only difference between the three types of
`IRBlock` is the phi nodes.

This commit changes the representation of `IRBlock` for `ssa` and
`aliased_ssa` so they become just wrappers around the `IRBlock` of their
previous layer. Most predicates in later layers are then computed from
the corresponding predicate of the preceding layer.
