f0608d829a 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.

bccfc24c4e 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.

975d7e0392 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
...

e9f9a7e10e 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.

3f2f3f5341 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.

9947bbb297 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.
