c4fb38b821 I don't think it makes any sense to assert that the target supports SSE3 here. 
The user (i.e. whoever generated a call to the intrinsic in the first place) is
essentially asking for a particular instruction to be placed in the assembler.
If that instruction won't execute on the target machine, that's their problem
not ours.  Two buildbots with processors that don't support SSE3 were barfing
on the apm.ll test in CodeGen/X86 because of this assertion.

d4b0873c06 Enable sibling call optimization of libcalls which are expanded during 
legalization time. Since at legalization time there is no mapping from
SDNode back to the corresponding LLVM instruction and the return
SDNode is target specific, this requires a target hook to check for
eligibility. Only x86 and ARM support this form of sibcall optimization
right now.

7e8a99b1c3 fix PR8686, accepting a 'b' suffix at the end of all the setcc 
instructions.  I choose to handle this with an asmparser hack,
though it could be handled by changing all the instruction definitions
to allow be "setneb" instead of "setne".  The asm parser hack is
better in this case, because we want the disassembler to produce
setne, not setneb.

7c601ded34 On X86, MEMBARRIER, MFENCE, SFENCE, LFENCE are not target memory intrinsics, 
so don't claim they are.  They are allocated using DAG.getNode, so attempts
to access MemSDNode fields results in reading off the end of the allocated
memory.  This fixes crashes with "llc -debug" due to debug code trying to
print MemSDNode fields for these barrier nodes (since the crashes are not
deterministic, use valgrind to see this).  Add some nasty checking to try
to catch this kind of thing in the future.

dca25f69ca trivial QoI improvement. On this invalid input: 
sahf	movl	344(%rdi),%r14d
we used to produce:

t.s:2:1: error: unexpected token in argument list

^

we now produce:

edb9d84dcc add targetoperand flags for jump tables, constant pool and block address 
nodes to indicate when ha16/lo16 modifiers should be used.  This lets
us pass PowerPC/indirectbr.ll.

The one annoying thing about this patch is that the MCSymbolExpr isn't
expressive enough to represent ha16(label1-label2) which we need on
PowerPC.  I have a terrible hack in the meantime, but this will have
to be revisited at some point.

Last major conversion item left is global variable references.
