Unify the 'constantFold' and 'fold' hooks on an operation into just 'fold'. This new unified fold hook will take constant attributes as operands, and may return an existing 'Value *' or a constant 'Attribute' when folding. This removes the awkward situation where a simple canonicalization like "sub(x,x)->0" had to be written as a canonicalization pattern as opposed to a fold.

A pass is introduced to lower to the LLVM.
Tests are moved out of C++ land and into mlir/test/Examples.
This allows better fitting within standard developer workflows.
