Andy, in a previous commit you made this into an ImmutablePass so that you could
add it to the PassManager, then in the next commit you left it a Pass but
removed the code that added it to the PM. If you do add it to the PM then the PM
should take care of deleting it, but it's also true that nothing in codegen

Add pseudo-registers for pairs, triples, and quads of D registers.
NEON loads and stores accept single and double spaced pairs, triples,
and quads of D registers. This patch adds new register classes to
accurately model those constraints:
Dn, Dn+1 Dn, Dn+2
----------------------
DPair DPairSpc
DTriple DTripleSpc
DQuad DQuadSpc
Also extend the existing QQ and QQQQ register classes to contains all Q
pairs and quads instead of just the aligned ones.
These new register classes will make it possible to accurately model
constraints on NEON loads and stores, and we can get rid of all the NEON
pseudo-instructions. The late scheduler will be able to accurately
model instruction dependencies from the explicit operands.
This more than doubles the number of ARM registers, but the backend
passes are quite good at handling this. The llc -O0 compile time only
regresses by 1.5%. Future work on register mask operands will recover
this regression.

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.

Add pass printer passes in the right place.
The pass pointer should never be referenced after sending it to
schedulePass(), which may delete the pass. To fix this bug I had to
clean up the design leading to more goodness.
You may notice now that any non-analysis pass is printed. So things like loop-simplify and lcssa show up, while target lib, target data, alias analysis do not show up. Normally, analysis don't mutate the IR, but you can now check this by using both -print-after and -print-before. The effects of analysis will now show up in between the two.
The llc path is still in bad shape. But I'll be improving it in my next checkin. Meanwhile, print-machineinstrs still works the same way. With print-before/after, many llc passes that were not printed before now are, some of these should be converted to analysis. A few very important passes, isel and scheduler, are not properly initialized, so not printed.
