by emitting the type planes before any constants (which could be constant
expressions involving undefined types!)

- Null values are implicitly encoded instead of explicitly, this makes
things more compact!
- More compactly represent ConstantPointerRefs
- Bytecode files are represented as:
Header|GlobalTypes|GlobalVars/Function Protos|Constants|Functions|SymTab
instead of
Header|GlobalTypes|Constants|GlobalVars/Function Protos|Functions|SymTab
which makes a lot of things simpler.
Writer changes:
- We now explictly encode versioning information in the bytecode files.
- This allows new code to read bytecode files produced by old code, but
new bytecode files can have enhancements such as the above. Although this
makes the reader a bit more complex (having to deal with old formats), the
writer only needs to be able to produce the most recent version.

* Renamed StatisticReporter.h/cpp to Statistic.h/cpp
* Broke constructor to take two const char * arguments instead of one, so
that indendation can be taken care of automatically.
* Sort the list by pass name when printing
* Make sure to print all statistics as a group, instead of randomly when
the statistics dtors are called.
* Updated ProgrammersManual with new semantics.

* 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

may be constructed by expressions of other types (and so the
contents of the primitive type planes must come after all types).
Use a helper function outputConstantsInPlane in outputConstants to
do this.

because the slot calculator is already part of the VMCore library.
* Rename incorporateMethod and purgeMethod to *Function

are being converted over to Function.

Method::inst_* is now in llvm/Support/InstIterator.h
GraphTraits specializations for BasicBlock and Methods are now in llvm/Support/CFG.h
