Chris Lattner 52a126cb3e Do not use the same variable name for two different variables in the
same scope.  This confused VC++ (and probably people too!).  Patch by
Morten Ofstad!

Reid Spencer 7c16caa336 Changes For Bug 352
Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

Chris Lattner f5d946eced Make use of "external" depth-first iterators to avoid revisiting nodes
multiple times.  This reduces the time to construct post-dominance sets a LOT.
For example, optimizing perlbmk goes from taking 12.9894s to 1.4074s.

Chris Lattner 8157505fae Rework 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. :)

the exit node.

Chris Lattner c86203ace3 - Split Dominators.h into Dominators.h & PostDominators.h

Chris Lattner 40eb9dafed - Cleaned up the interface to AnalysisUsage to take analysis class names
instead of ::ID's.
 - Pass::getAnalysis<> now no longer takes an optional argument

Chris Lattner 2675007573 * Standardize how analysis results/passes as printed with the print() virtual
methods
* Eliminate AnalysisID:  Now it is just a typedef for const PassInfo*
* Simplify how AnalysisID's are initialized
* Eliminate Analysis/Writer.cpp/.h: incorporate printing functionality into
  the analyses themselves.

Chris Lattner c8e665431b * Rename MethodPass class to FunctionPass
- Rename runOnMethod to runOnFunction
* Transform getAnalysisUsageInfo into getAnalysisUsage
  - Method is now const
  - It now takes one AnalysisUsage object to fill in instead of 3 vectors
    to fill in
  - Pass's now specify which other passes they _preserve_ not which ones
    they modify (be conservative!)
  - A pass can specify that it preserves all analyses (because it never
    modifies the underlying program)
* s/Method/Function/g in other random places as well

* Add #includes that are now neccesary because BasicBlock.h doesn't include
  InstrTypes.h anymore

Chris Lattner ba1c1f2fb6 Pull predecessor and successor iterators out of the CFG*.h files, and plop them into
