where are least one of them is static/internal.

b1b4262387 * Remove dead code from ExprTypeConvert.cpp 
- 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

1e2ddcf741 Hash pointer values to a sequence number to get identical results from 
lli and llc.  This is controlled with options -tracehash on|off.

Also, added an option to specify which functions should be traced.
Particularly useful to reduce output volume in basic-block tracing.

"This testcase caused instcombine to fail because it got the same instruction on

Since the inst stayed on the worklist, as soon as it came back up to be

f57b845547 * Rename MethodPass class to FunctionPass

* Transform getAnalysisUsageInfo into getAnalysisUsage

    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)

  removed in the future.
* Moved the computation of "Scalars" into transformFunctionBody so
  transformFunction didn't have to recompute it.
* Implement the node mapping calculation in preparation to calculate
  PoolDescriptors to pass to transformFunctionBody
* Print out the node mapping [it looks right!]
* Other minor changes

9d3493e533 Implement the first batch of transformations to the methods. So far it: 
* Converts malloc instructions to poolalloc
 * Converts free instructions to poolfree
 * Convert calls to call the new cloned hacked up versions

Note that this does not modify hacked up stuff yet, just the top level
function

a744451856 Correctly clone the function with the extra argument types. Now we need 
to modify the function next.

This also properly recycles functions so that we don't get exponential
code blowup in the common case.
