dfd0d44c99 Another portability fix provided via Casey Carter: 
ISSUE: getTimeRecord in lib/VMCore/Pass.cpp uses timeval and
gettimeofday() without including sys/time.h.

ACTION: Include sys/time.h.

f743017498 - PassManager prints analysis sets nicer

1ae38466e6 - Fighting with linking problem due to removing the ::ID elements. Now the 
implementation .cpp files for analyses are not being included into gccas
    and friends because it is linking to the .a file and there is no explicit
    symbol reference to bring in the .o file.  The new IncludeFile hack is the
    result.

a7bcc10581 * Move some code from Pass.cpp to PassManagerT.h 
* Implement stuff so that code can declare that they only depend on the CFG of
  a function, not on anything else.  This speeds up GCCAS a lot.

fd9fefa8f6 * PassInfo is allowed to be missing now (ie, not all passes need be registered) 
* getPassName uses PassInfo if it's available
* PassInfo is now cached in the pass so that it is only looked up once, maximum

ec2780457d * 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.

6285ebca7d Add a new command line option for PassManager using utilities. 
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.

c64ef6740a * Add a stub to FunctionPass so that subclasses can declare that they do not 
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

536cf1b13f * 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
