d263602463 Remove most of the uses of SDOperandPtr, usually replacing it with a 
simple const SDOperand*, which is what's usually needed.

For AddNodeIDOperands, which is small, just duplicate the function to
accept an SDUse*.

For SelectionDAG::getNode - Add an overload that accepts SDUse* that
copies the operands into a temporary SDOperand array, but also has
special-case checks for 0 through 3 operands to avoid the copy in
the common cases.

1d321b8875 Removed ImmutableMap::SlimFind and replaced it with ImmutableMap::lookup. The new method does the same thing, except that it returns a pointer to the mapped data type, and not to an internal tree node.

a43d6758ac Fixed generating incorrect aligned stores that I backout of r53031 
that fixed problems in EmitStackConvert where the source and target type
have different alignment by creating a stack slot with the max
alignment of source and target type.

3ea6f15708 Rather than having a different custom legalization 
hook for each way in which a result type can be
legalized (promotion, expansion, softening etc),
just use one: ReplaceNodeResults, which returns
a node with exactly the same result types as the
node passed to it, but presumably with a bunch of
custom code behind the scenes.  No change if the
new LegalizeTypes infrastructure is not turned on.

aac5c915ed Linux also does not require exception handling 
moves in order to get correct debug info.  Since
I can't imagine how any target could possibly
be any different, I've just stripped out the
option: now all the world's like Darwin!

1f6148a84c - Remove calls to copyKillDeadInfo which is an N^2 function. Instead, propagate kill / dead markers as new instructions are constructed in foldMemoryOperand, convertToThressAddress, etc. 
- Also remove LiveVariables::instructionChanged, etc. Replace all calls with cheaper calls which update VarInfo kill list.

7c3920e692 - Add LiveVariables::replaceKillInstruction. This does a subset of instructionChanged. That is, it only update the VarInfo.kills if the new instruction is known to have the correct dead and kill markers. 
- CommuteInstruction copies kill / dead markers over to new instruction. So use replaceKillInstruction instead.

604f9f722d Make LiveVariables even more optional, by making it optional in the call to TargetInstrInfo::convertToThreeAddressInstruction 
Also, if LV isn't around, then TwoAddr doesn't need to be updating flags, since they won't have been set in the first place.

741cda0ac8 Replace a few uses of SelectionDAG::getTargetNode with 
SelectionDAG::SelectNodeTo in the instruction selector. This
updates existing nodes in place instead of creating new ones.

Go back to selecting ISD::DBG_LABEL nodes into
TargetInstrInfo::DBG_LABEL nodes instead of leaving them
unselected, now that SelectNodeTo allows us to update them
in place.

21e2a711e3 Add a new getMergeValues method that does not need 
to be passed the list of value types, and use this
where appropriate.  Inappropriate places are where
the value type list is already known and may be
long, in which case the existing method is more
efficient.

9e88ac84bf Implement suggestions from Chris: 
- Use a more accurate heuristic for the size of the hashtable.
  - Use bitwise and instead of modulo since the size is a power of two.
  - Use new[] instead of malloc().

c8097f8c8c Split ISD::LABEL into ISD::DBG_LABEL and ISD::EH_LABEL, eliminating 
the need for a flavor operand, and add a new SDNode subclass,
LabelSDNode, for use with them to eliminate the need for a label id
operand.

Change instruction selection to let these label nodes through
unmodified instead of creating copies of them. Teach the MachineInstr
emitter how to emit a MachineInstr directly from an ISD label node.

This avoids the need for allocating SDNodes for the label id and
flavor value, as well as SDNodes for each of the post-isel label,
label id, and label flavor.
