- Reenable gep (gep x) -> x
- Make instcombine do dead instruction elimination where it's really
easy. Now visitors don't have to ensure they aren't not processing
dead instructions.

* Internalize global variables with initializers
* Add new stat to track global variable internalization
* Only count functions that were not internal before in internalized function
count

* Correctly delete TypeHandles in AsmParser. In addition to not leaking
memory, this prevents a bug that could have occurred when a type got
resolved that the constexpr was using
* Check for errors in the AsmParser instead of hitting assertion failures
deep in the code
* Simplify the interface to the ConstantExpr class, removing unneccesary
parameters to the ::get* methods.
* Rename the 'getelementptr' version of ConstantExpr::get to
ConstantExpr::getGetElementPtr

old call instruction
* Implement conversion of return values for calls. This fixes bug:

which was caused by us not running the "drop references of dead
instructions" code when there were no basic blocks that were dead.
We still don't want to do some of the stuff we do if there are dead
basic blocks, but we DO want to drop references of dead instructions,
so we factor the common code out to a new method.

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.

are to show up in opt or analyze

This change fixes programs that have multiple functions named the same thing,
where are least one of them is static/internal.

- 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
