the current function on its own, rather than relying on the SelectionDAG.

0a3ae5c0f2 Remove the FlaggedNodes member from SUnit. Instead of requiring each SUnit 
to carry a SmallVector of flagged nodes, just calculate the flagged nodes
dynamically when they are needed.

The local-liveness change is due to a trivial scheduling change where
the scheduler arbitrary decision differently.

aa9f1836d9 Don't allow the restore point to be placed after terminators. With this change, 
MultiSource/Applications is clean with the prealloc splitter.  Some failures
remain in SPEC.

de9fdff884 Extend InlineAsm::C_Register to allow multiple specific registers 
(actually, code already all worked, only the comment
changed).  Use this to implement 'A' constraint on x86.

9dc2bd7973 Modify the intrinsics pattern to separate out the "return" types from the 
"parameter" types. An intrinsic can now return a multiple return values like
this:

  def add_with_overflow : Intrinsic<[llvm_i32_ty, llvm_i1_ty],
                                    [LLVMMatchType<0>, LLVMMatchType<0>]>;

229c65c05b Move the code that inserts X87 FP_REG_KILL instructions from a 
special-purpose hook to a new pass. Also, add check to see if any
x87 virtual registers are used, to avoid doing any work in the
common case that no x87 code is needed.

4e70a21580 Simplify SplitVecRes_EXTRACT_SUBVECTOR. This means 
that it no longer handles non-power-of-two vectors.
However it previously only handled them sometimes,
depending on obscure numerical relationships between
the index and vector type.  For example, for a vector
of length 6, it would succeed if and only if the
index was an even multiple of 6.  I consider this
more confusing than useful.

291ea92cc4 In ScheduleDAGRRList::CopyAndMoveSuccessors, create the SUnit for the load 
before creating the SUnit for the operation that it was unfolded from. This
allows each SUnit to have all of its predecessor SUnits available at the time
it is created. I don't know yet if this will be absolutely required, but it
is a little tidier to do it this way.
