eacdef21c6 Revert r53367, which was breaking things.

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.

1373c1c395 hasAnyUseOfValue can check SDUse nodes of its users directly instead 
of examining every operand of every user.

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.

7705ea33e4 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.

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.

dd4b47c9b2 Don't use an expensive check for two-address-ness when we have the information sitting around to determine it much more quickly,
