1. Add support for defining Pattern's, which can match expressions when there
is no instruction that directly implements something. Instructions usually
implicitly define patterns.
2. Add support for defining SDNodeXForm's, which are node transformations.
This seperates the concept of a node xform out from the existing predicate

two for OR/XOR by an arbitrary immediate.
