Fix dominance calculation
Fixes dominance calculation when there is a forward arc from an
unreachable block A to a reachable block B. Before this fix, we would
say that B is not dominated by the graph entry node, and instead say
that the immediate dominator of B is the psuedo-entry node of the
augmented CFG.
The fix:
- Dominance is defined in terms of a traversal from the entry block
of the CFG. So the forward DFS should start from the function
entry block, not the pseudo-entry-block.
- When following edges backward during dominance calculations, only go to
nodes that are actually reachable in the forward traversal.
Important: the sense of reachability flips around when computing
post-dominance.

Use pseudo entry and pseudo exit blocks for dominance.
For dominance calculations we use an "augmented" CFG
where we always add a pseudo-entry node that is the predecessor
in the augmented CFG to any nodes that have no predecessors in the
regular CFG. Similarly, we add a pseudo-exit node that is the
predecessor in the augmented CFG that is a successor to any
node that has no successors in the regular CFG.
Pseudo entry and exit blocks live in the Function object.
Fixes a subtle problem where we were implicitly creating
the block_details for the pseudo-exit node since it didn't
appear in the idoms map, and yet we referenced it. In such a case the
contents of the block details could be garbage, or zero-initialized.
That sometimes caused incorrect calculation of immediate dominators
and post-dominators. For example, on a debug build where the details
could be zero-initialized, the dominator of an unreachable block would
