llvm::SwitchInst
Renamed methods caseBegin, caseEnd and caseDefault with case_begin, case_end, and case_default.
Added some notes relative to case iterators.

Taken into account Duncan's comments for r149481 dated by 2nd Feb 2012:
http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20120130/136146.html
Implemented CaseIterator and it solves almost all described issues: we don't need to mix operand/case/successor indexing anymore. Base iterator class is implemented as a template since it may be initialized either from "const SwitchInst*" or from "SwitchInst*".
ConstCaseIt is just a read-only iterator.
CaseIt is read-write iterator; it allows to change case successor and case value.
Usage of iterator allows totally remove resolveXXXX methods. All indexing convertions done automatically inside the iterator's getters.
Main way of iterator usage looks like this:
SwitchInst *SI = ... // intialize it somehow
for (SwitchInst::CaseIt i = SI->caseBegin(), e = SI->caseEnd(); i != e; ++i) {
BasicBlock *BB = i.getCaseSuccessor();
ConstantInt *V = i.getCaseValue();
// Do something.
}
If you want to convert case number to TerminatorInst successor index, just use getSuccessorIndex iterator's method.
If you want initialize iterator from TerminatorInst successor index, use CaseIt::fromSuccessorIndex(...) method.
There are also related changes in llvm-clients: klee and clang.

SwitchInst refactoring.
The purpose of refactoring is to hide operand roles from SwitchInst user (programmer). If you want to play with operands directly, probably you will need lower level methods than SwitchInst ones (TerminatorInst or may be User). After this patch we can reorganize SwitchInst operands and successors as we want.
What was done:
1. Changed semantics of index inside the getCaseValue method:
getCaseValue(0) means "get first case", not a condition. Use getCondition() if you want to resolve the condition. I propose don't mix SwitchInst case indexing with low level indexing (TI successors indexing, User's operands indexing), since it may be dangerous.
2. By the same reason findCaseValue(ConstantInt*) returns actual number of case value. 0 means first case, not default. If there is no case with given value, ErrorIndex will returned.
3. Added getCaseSuccessor method. I propose to avoid usage of TerminatorInst::getSuccessor if you want to resolve case successor BB. Use getCaseSuccessor instead, since internal SwitchInst organization of operands/successors is hidden and may be changed in any moment.
4. Added resolveSuccessorIndex and resolveCaseIndex. The main purpose of these methods is to see how case successors are really mapped in TerminatorInst.
4.1 "resolveSuccessorIndex" was created if you need to level down from SwitchInst to TerminatorInst. It returns TerminatorInst's successor index for given case successor.
4.2 "resolveCaseIndex" converts low level successors index to case index that curresponds to the given successor.
Note: There are also related compatability fix patches for dragonegg, klee, llvm-gcc-4.0, llvm-gcc-4.2, safecode, clang.

This patch is a big refactoring of llvm-diff. It doesn't add new features, but it re-organizes the old features, so I can insert the MetadataEngine to use the same infrastructure.

Check in a couple of changes that I apparently never committed:
- teach DifferenceEngine to unify successors of calls and invokes
in certain circumstances
- basic blocks actually don't have their own numbering; did that change?
- add llvm-diff to the Makefile and CMake build systems

it establishes a context and does a complaining diff. Also make sure we
unify the prelude and postlude of a diff after a block-diff call.

When unifying instructions during a block diff, actually complain about
any differences we see. This should only happen if there are "non-structural"
differences between the instructions, i.e. differences which wouldn't cause
diff to return true.

Somehow I was getting reasonable results for the test cases I was interested
in despite not ever incrementing any path costs, so that the only nonzero costs
arose from the all-left path in the first column. Anyway. Perform the diff
starting from the beginning of the block to avoid capturing (say) loads of
allocas.
Vastly improves diff results on code that hasn't been mem2reg'ed.

Add the llvm-diff tool, which performs a relatively naive structural
diff of a function. There's a lot of cruft in the current version, and
it's pretty far from perfect, but it's usable.
Currently only capable of comparing functions. Currently ignores metadata.
Currently ignores most attributes of functions and instructions.
Patches welcome.
