80f6966c7f - 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.

e10fc737ca 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.

6ba50d7fc1 hasAnyUseOfValue can check SDUse nodes of its users directly instead 
of examining every operand of every user.

679872b05f Move MemoryVT out of LSBaseNode into MemSDNode, allowing the 
getMemOperand function to be moved into the base class as well
and made non-virtual.

9eae9520a9 Remove a FIXME: we really need to use const_data section on darwin for 
constant pool, if relocation model is not static. This directly maps to
the way how GCC works.

the relationship.

f6e651fcf2 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.

50a64de51e Don't use an expensive check for two-address-ness when we have the information sitting around to determine it much more quickly, 
This speeds up the local register allocator from 0.37s to 0.31s on instcombine.
