aa7976199c - Changes how function livein's are handled, they now have a start index of 0.
- When coalescing a copy MI, if its destination is "dead", propagate the
  property to the source MI's destination if there are no intervening uses.
- Detect dead function live-in's and remove them.

831e0374a7 switch the VRBaseMap in the scheduler from an std::map to a DenseMap. This

3f97eb449b Introduce new UnarySDNode/BinarySDNode/TernarySDNode nodes, which coallocate
their operands with the node itself.  This reduces malloc traffic for operand
lists.  This reduces isel time on kc++ from 2.6164 to 2.5570s, about 2.3%.

bc2e26241d Add a new SDNode ctor and InitOperands method. This allows the operands for
an SDNode to be allocated as part of the node itself, instead of being a
separate new[]'d object.  Switch HandleSDNode, LoadSDNode, and StoreSDNode
to use this mechanism.  This saves one heap allocation and free for each node
of this type that is allocated.  This reduces isel time from 2.7638 to 2.6164s
on kc++, which is a 5.6% speedup.

b10308e440 Propagate changes from my local tree. This patch includes:
1. New parameter attribute called 'inreg'. It has meaning "place this
parameter in registers, if possible". This is some generalization of
gcc's regparm(n) attribute. It's currently used only in X86-32 backend.
2. Completely rewritten CC handling/lowering code inside X86 backend.
Merged stdcall + c CCs and fastcall + fast CC.
3. Dropped CSRET CC. We cannot add struct return variant for each
target-specific CC (e.g. stdcall + csretcc and so on).
4. Instead of CSRET CC introduced 'sret' parameter attribute. Setting in
on first attribute has meaning 'This is hidden pointer to structure
return. Handle it gently'.
5. Fixed small bug in llvm-extract + add new feature to
FunctionExtraction pass, which relinks all internal-linkaged callees
from deleted function to external linkage. This will allow further
linking everything together.

NOTEs: 1. Documentation will be updated soon.
       2. llvm-upgrade should be improved to translate csret => sret.
          Before this, there will be some unexpected test fails.

instances of IntegerType that are not considered isInteger! :)

Rename LHSBB/RHSBB to TrueBB/FalseBB.  Allow the RHS value to be null,
in which case the LHS is treated as a bool.

51dabfb283 When SimplifySetCC was moved to the DAGCombiner, it was never removed from
SelectionDAG and it has since bitrotted.  Remove the copy from SelectionDAG.
Next, remove the constant folding piece of DAGCombiner::SimplifySetCC into
a new FoldSetCC method which can be used by getNode() and SimplifySetCC.

This fixes obscure bugs.

24446e253a Merging ISD::LOAD and ISD::LOADX. Added LoadSDNode to represent load nodes.
Chain and address ptr remains as operands. SrcValue, extending mode, extending
VT (or rather loaded VT before extension) are now instance variables of
LoadSDNode.

Introduce load / store addressing modes to represent pre- and post-indexed
load and store. Also added an additional operand offset that is only used in
post-indexed mode (i.e. base ptr += offset after load/store).

Added alignment info (not yet used) and isVolatile fields.
