* Do not skip the instruction immediately after a folded instruction.  This

definitions must still occur before function bodies, but the wierd keyword is
no longer neccesary.

* Allow elimination of getelementptr X, uint 0 (which is a noop)

to make debugging output a lot nicer.

Now for llc, gccas, analyze, opt, etc you can specify the -time-passes
command line option that outputs a timing summary report that indicates
how long each pass takes to execute.

Tighten up the AnalysisUsage of lots of passes, primarily to correctly indicate whether or not they invalidate the CFGA

  modify the CFG.  It currently does nothing, but will in the future.
* Changes to make the public PassManager.h be MUCH smaller, and devoid of
  implementation details.  Now PassManager is just a Pimpl class that wraps
  PassManagerT<Module>, but lib/VMCore/Pass.cpp is now the only class that
  has to #include PassManagerT.h
