8ee9065162 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

ea857029ea Remove ImmediateDominator analysis. The same information can be obtained from DomTree. A lot of code for 
constructing ImmediateDominator is now folded into DomTree construction.

This is part of the ongoing work for PR217.

7cf9d12f2e Add DomSet back, and revert the changes to LoopSimplify. Apparently the 
ETForest updating mechanisms don't work as I thought they did.  These changes
will be reapplied once the issue is worked out.

7f6a73eb5c Added an automatic cast to "std::ostream*" etc. from OStream. We then can 
rework the hacks that had us passing OStream in. We pass in std::ostream*
instead, check for null, and then dispatch to the correct print() method.

560366562b 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
   with the macros in IncludeFile.h
This gets us a consistent mechanism throughout LLVM for ensuring linkage.
Next step is to make sure its used in enough places.

2c6d390a60 Change from using a stub function to a stub variable for passing to the 
IncludeFile hack to ensure linkage of analysis passes. This works around
some -pedantic warnings about assigning an object to a function.

d4abe8d28a The recalclulate method was a nasty hack that was once used by the -cee pass, 
which never worked itself.  The cee pass still doesn't work, but it doesn't use
this method anymore anyway, so eliminate the method.

e7c33c0f65 Rework dominator and post dominator information so that we do not have to 
unify all exit nodes of a function to compute post-dominance information.
This does not work with functions that have both unwind and return nodes,
because we cannot unify these blocks.  The new implementation is better
anyway. :)
