Tutorial Linalg1: implement conversion to the LLVM Dialect

    Implement conversion from the Linalg dialect to the LLVM dialect using a simple
    set of DialectOpConverters and by plugging them into the dialect conversion
    infrastructure.  View and Range Linalg types are converted into descriptors
    that store the dynamic values in an LLVM aggregate type, similarly to memrefs.
    Slice operations create new descriptors based on the original descriptors and
    thus remove the constraint on ViewTypes not being acceptable as function
    arguments.
