  - Added new method Type::isIntegral() that is the same as isInteger, but
    also accepts bool.

* Add support for different "PassType's"
* Add new RegisterOpt/RegisterAnalysis templates for registering passes that
  are to show up in opt or analyze
* Register Analyses now
* Change optimizations to use RegisterOpt instead of RegisterPass
* Add support for different "PassType's"

   - I->use_empty() can never be true because of the IHolder's
* Fix bug: test/Regression/Transforms/LevelRaise/2002-07-16-SourceAndDestCrash.ll
   - Add a new NewCasts member to VMC to keep track of casts that have been
     created and to ensure there is always a reference to the cast.
   - Extend ValueHandle a bit so it can be used in an STL container
   - Make sure we destroy the ValueMapCache before verifying the function
     in LevelRaise.cpp

llvm-svn: 2936

  - Verify the function every time it is exprconverted if DEBUG is on
  - Provide a way to start exprconversion AT a specific instruction.

be put either before or after a load.  We chose to cast the value loaded
instead of the pointer to load from.

Fixes bug: test/Regression/Transforms/LevelRaise/2002-05-10-LoadPeephole.ll

* Make cast-of-self-ty DCE the dead cast instruction immediately instead of
  waiting for it to be DCE'd by another sweep over the function.  This speeds
  this up noticably.

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

llvm-svn: 2386

llvm-svn: 2378

  - 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

Remove extraneous #includes of llvm/Assembly/Writer

are being converted over to Function.

would be generated.  In this case, however, it wasn't, so bad things happened.

* Output nicer message for dead code eliminated when debugging

* Unsized arrays are a thing of the past, remove DoInsertArrayCast family
* Remove cases were we would get into infinite loops because we would insert a cast
  which would then be removed, inserting a different cast, ad infinitum...
* Remove some code that should be redundant with ExprTypeConvert code
