Loosen our check here.  Local regalloc only cares that the reg is used and def'd by the same instruction, but about the details of
the relationship.

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.

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.
