7d9f2b93a3 This test case: 
long test(long x) { return (x & 123124) | 3; }

Currently compiles to:

_test:
        orl     $3, %edi
        movq    %rdi, %rax
        andq    $123127, %rax
        ret

This is because instruction and DAG combiners canonicalize

  (or (and x, C), D) -> (and (or, D), (C | D))

However, this is only profitable if (C & D) != 0. It gets in the way of the
3-addressification because the input bits are known to be zero.

6b7f39c895 remove 300 lines of code that is now dead in the MSP430 backend 
now that isel handles chains more aggressively.  This also
allows us to make isLegalToFold non-virtual.

d1b7382983 Fix some issues in WalkChainUsers dealing with 
CopyToReg/CopyFromReg/INLINEASM.  These are annoying because
they have the same opcode before an after isel.  Fix this by
setting their NodeID to -1 to indicate that they are selected,
just like what automatically happens when selecting things that
end up being machine nodes.

With that done, give IsLegalToFold a new flag that causes it to
ignore chains.  This lets the HandleMergeInputChains routine be
the one place that validates chains after a match is successful,
enabling the new hotness in chain processing.  This smarter
chain processing eliminates the need for "PreprocessRMW" in the
X86 and MSP430 backends and enables MSP to start matching it's
multiple mem operand instructions more aggressively.

I currently #if out the dead code in the X86 backend and MSP 
backend, I'll remove it for real in a follow-on patch.

The testcase changes are:
  test/CodeGen/X86/sse3.ll: we generate better code
  test/CodeGen/X86/store_op_load_fold2.ll: PreprocessRMW was 
      miscompiling this before, we now generate correct code
      Convert it to filecheck while I'm at it.
  test/CodeGen/MSP430/Inst16mm.ll: Add a testcase for mem/mem
      folding to make anton happy. :)

c4f7ec85ec When expanding an expression such as (A + B + C + D), sort the operands 
by loop depth and emit loop-invariant subexpressions outside of loops.

82dd3d38d9 Fix the xfail I added a couple of patches back. The issue 
was that we weren't properly handling the case when interior
nodes of a matched pattern become dead after updating chain
and flag uses.  Now we handle this explicitly in 
UpdateChainsAndFlags.
