9fc5cdf77c split dom frontier handling stuff out to its own DominanceFrontier header,
so that Dominators.h is *just* domtree.  Also prune #includes a bit.

2ab36d3502 Begin adding static dependence information to passes, which will allow us to
perform initialization without static constructors AND without explicit initialization
by the client.  For the moment, passes are required to initialize both their
(potential) dependencies and any passes they preserve.  I hope to be able to relax
the latter requirement in the future.

63d3659a44 Remove unneeded debug in PostDominator runOnFunction()
The information is already available with "opt -analyze". The DominatorTree
does also not have this in its runOnFunction. So they behave now
more consistent.

DenseMap instead of an std::map.  This speeds up postdomtree

for example, domfrontier by 11%, mem2reg by 4% and ADCE by 6%.

1. Fix the macros in IncludeFile.h to put everything in the llvm namespace
2. Replace the previous explicit mechanism in all the .h and .cpp files

Next step is to make sure its used in enough places.
