250c1d8734 - Replace use of std::map<std::string, ..> with StringMap. Replace use of std::map with DenseMap, std::set with SmallPtrSet. This results in minor speed up. 
- Some code clean up.

b9c33c3229 Simplify hasNUsesOfValue and hasAnyUsesOfValue even more. This 
makes their special-case checks of use_size() less beneficial,
so remove them. This eliminates all but one use of use_size(),
which is in AssignTopologicalOrder, which uses it only once for
each node, and so can reasonably afford to recompute it, as
this allows the UsesSize field of SDNode to be removed
altogether.

1ea58a52a4 Move MemoryVT out of LSBaseNode into MemSDNode, allowing the 
getMemOperand function to be moved into the base class as well
and made non-virtual.

492f276cbc Move the IsVolatile and SVOffset fields into the MemSDNode base 
class, and store IsVolatile and Alignment in a more compact form.
This makes AtomicSDNode slightly larger, but it shrinks LoadSDNode
and StoreSDNode, which are much more common and are the largest of
the SDNode subclasses. Also, this lets the isVolatile() and
getAlignment() accessors be non-virtual.

6fa6a32e4e Add a little wrapper header that is put around bc files when emitting 
bc files for modules with a target triple that indicates they are for
darwin.  The reader unconditionally handles this, and the writer could
turn this on for more targets if we care.

This change has two benefits for darwin:

1) it allows us to encode the cpu type of the file in an easy to read
   place that doesn't require decoding the bc file.
2) it works around a bug (IMO) in darwin's AR where it is incapable of
   handling files that are not a multiple of 8 bytes long.  BC files
   are only guaranteed to be multiples of 4 bytes long.

8e5f2c6f65 Pool-allocation for MachineInstrs, MachineBasicBlocks, and 
MachineMemOperands. The pools are owned by MachineFunctions.

This drastically reduces the number of calls to malloc/free made
during the "Emit" phase of scheduling, as well as later phases
in CodeGen. Combined with other changes, this speeds up the
"instruction selection" phase of CodeGen by 10% in some cases.

6d9cdd5617 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.
