River Riddle 35807bc4c5 NFC: Introduce new ValuePtr/ValueRef typedefs to simplify the transition to Value being value-typed.
This is an initial step to refactoring the representation of OpResult as proposed in: https://groups.google.com/a/tensorflow.org/g/mlir/c/XXzzKhqqF_0/m/v6bKb08WCgAJ

This change will make it much simpler to incrementally transition all of the existing code to use value-typed semantics.

Nicolas Vasilache 0bd6390b54 Deprecate linalg.subview in favor of std.subview
This CL uses the now standard std.subview in linalg.
Two shortcuts are currently taken to allow this port:
1. the type resulting from a view is currently degraded to fully dynamic to pass the SubViewOp verifier.
2. indexing into SubViewOp may access out of bounds since lowering to LLVM does not currently enforce it by construction.

These will be fixed in subsequent commits after discussions.

Andy Davis 5cf6e0ce7f Adds std.subview operation which takes dynamic offsets, sizes and strides and returns a memref type which represents sub/reduced-size view of its memref argument.
This operation is a companion operation to the std.view operation added as proposed in "Updates to the MLIR MemRefType" RFC.

Nicolas Vasilache 72040bf7c8 Update Linalg to use std.view
Now that a view op has graduated to the std dialect, we can update Linalg to use it and remove ops that have become obsolete. As a byproduct, the linalg buffer and associated ops can also disappear.

Nicolas Vasilache 98226e62ec Standardize Linalg transformations to take an OpBuilder and an OperationFolder - NFC
This will be used to specify declarative Linalg transformations in a followup CL. In particular, the PatternRewrite mechanism does not allow folding and has its own way of tracking erasure.

Nicolas Vasilache 5b03e692f6 Decouple Linalg promotion from Linalg tiling - NFC
This CL creates a new Linalg promotion pass that operates on SubViewOp and decouples it from Linalg tiling. This is mostly moving code around.
