For PR780:
...
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.

Fix PR681 by using the standard Lengauer and Tarjan algorithm for dominator

set construction, rather than intersecting various std::sets. This reduces
the memory usage for the testcase in PR681 from 496 to 26MB of ram on my
darwin system, and reduces the runtime from 32.8 to 0.8 seconds on a
2.5GHz G5. This also enables future code sharing between Dom and PostDom
now that they share near-identical implementations.
