Handle unreachable code in the dominates functions. This changes users when
...
needed for correctness, but still doesn't clean up code that now unnecessary
checks for reachability.

verifier does. This correctly handles invoke.
Thanks to Duncan, Andrew and Chris for the comments.

perform initialization without static constructors AND without explicit initialization

Fix (at least) quadratic worst-case complexity in DominanceFrontier::splitBlock:
...
don't visit all blocks in the function, and don't iterate over the split blocks'
predecessor lists for each block visited.
Also, remove the special-case test for the entry block. Splitting the entry
block isn't common enough to make this worthwhile.
This fixes a major compile-time bottleneck which is exposed now that
LoopSimplify isn't being redundantly run both before and after
DominanceFrontier.

full checking.
