4bb87cbac5 SmallPtrSet: Reuse DenseMapInfo's pointer hash function instead of inventing a bad one ourselves. 
DenseMap's hash function uses slightly more entropy and reduces hash collisions
significantly.  I also experimented with Hashing.h, but it didn't gave a lot of
improvement while being much more expensive to compute.

1356041296 Use a heavy hammer to fix PR12573. 
If the loop contains invoke instructions, whose unwind edge escapes the loop,
then don't try to unswitch the loop. Doing so may cause the unwind edge to be
split, which not only is non-trivial but doesn't preserve loop simplify
information.

Fixes PR12573

b512263596 loop-reduce: Add an early bailout to catch extremely large loops. 
This introduces a threshold of 200 IV Users, which is very
conservative but should be sufficient to avoid serious compile time
sink or stack overflow. The llvm test-suite with LTO never exceeds 190
users per loop.

The bug doesn't relate to a specific type of loop. Checking in an
arbitrary giant loop as a unit test would be silly.

Fixes rdar://11262507.

d16ce17711 Fixes a problem in instruction selection with testing whether or not the 
transformation:

(X op C1) ^ C2 --> (X op C1) & ~C2 iff (C1&C2) == C2

should be done.  

This change has been tested:
 Using a debug+asserts build:

   using this clang to build a release version of clang
 Using the release+asserts clang-with-clang build:

Checking in because Evan wants it checked in.  Test case forthcoming after

613dfb219c SlotIndexes used to store the index list in a crufty custom linked-list. I can't 
for the life of me remember why I wrote it this way, but I can't see any good
reason for it now. This patch replaces the custom linked list with an ilist.

This change should preserve the existing numberings exactly, so no generated code
should change (if it does, file a bug!).
