7296225414 Add a verifyAnalysis to LoopInfo, LoopSimplify, and LCSSA form that verify 
that these passes are properly preserved.

Fix several transformation passes that claimed to preserve LoopSimplify
form but weren't.

382f174be1 Move getUniqueExitBlocks from LoopBase to Loop, since they depend on 
LoopSimplify form, which is currently only available on Loops (and
not MachineLoops). Also, move the code out of the header file.

66c853f17f Change PHINode::hasConstantValue to have a DominatorTree argument 
instead of a bool argument, and to do the dominator check itself.
This makes it eaiser to use when DominatorTree information is
available.

d7cc632fcf Implement support for X86II::MO_GOT_ABSOLUTE_ADDRESS. We get very 
different formatting from the old asmprinter, but it should be 
semantically the same.  We used to get:

	popl	%eax
	addl	$_GLOBAL_OFFSET_TABLE_ + [.-.Lllvm$6.$piclabel], %eax
...

Now we get:

	popl	%eax
.Lpicbaseref6:
	addl	$(_GLOBAL_OFFSET_TABLE_ + (.Lpicbaseref6 - .Lllvm$6.$piclabel)), %eax
...

3ac0c58031 In C++, code is not allowed to call main. In C it is, this 
simplifylibcalls optimization is thus valid for C++ but not C.
It's not important enough to worry about for C++ apps, so just
remove it.

6d0baa578a Set the 'cached digest' flag after computing the digest for an 
ImutAVLTree.  This was accidentally left out, and essentially caused
digest caching to be ignored in ImmutableMap and ImmutableSet (this
bug was detected from shark traces that showed ComputeDigest was in
the hot path in the clang static analyzer).

This reduces the running time of the clang static analyzer on an
example benchmark by ~32% for both RegionStore (field-sensitivty) and
BasicStore (without field-sensitivity).

3c7f6b706c Fixed a test that ensures the LocalRewriter does not attempt to 
avoid reloads by reusing clobbered registers.

This was causing issues in 256.bzip2 when compiled with PIC for
a while (starting at r78217), though the problem has since been masked.

27616c3c80 Now Bitcode reader bug is fixed. Reapply 80839.

Use FoldingSetNode to unique MDNodes in a context.
Use CallbackVH hooks to update context's MDNodeSet appropriately.

1c6706b750 Added opaque 32-, 48-, and 80-bit memory operand types to the X86 
instruction tables to support segmented addressing (and other objects
of obscure type).
Modified the X86 assembly printers to handle these new operand types.
Added JMP and CALL instructions that use segmented addresses.
