Stephen Neuendorffer 34d12c15f7 [MLIR] Better message for FuncOp type mismatch
Previously the actual types were not shown, which makes the message
difficult to grok in the context of long lowering chains.  Also, it
appears that there were no actual tests for this.

Diego Caballero a611f9a5c6 [mlir] Fix call op conversion in bare-ptr calling convention
We hit an llvm_unreachable related to unranked memrefs for call ops
with scalar types. Removing the llvm_unreachable since the conversion
should gracefully bail out in the presence of unranked memrefs. Adding
tests to verify that.

Nicolas Vasilache e3de249a4c [mlir] Add a subtensor operation
This revision introduces a `subtensor` op, which is the counterpart of `subview` for a tensor operand. This also refactors the relevant pieces to allow reusing the `subview` implementation where appropriate.

This operation will be used to implement tiling for Linalg on tensors.

Stephen Neuendorffer 47df8c57e4 [MLIR] Updates around MemRef Normalization
The documentation for the NormalizeMemRefs pass and the associated MemRefsNormalizable
traits was confusing and not on the website.  This update clarifies the language
around the difference between a MemRef Type, an operation that accesses the value of
MemRef Type, and better documents the limitations of the current implementation.
This patch also includes some basic debugging information for the pass so people
might have a chance of figuring out why it doesn't work on their code.

MaheshRavishankar c694588fc5 [mlir][Linalg] Add pattern to tile and fuse Linalg operations on buffers.
The pattern is structured similar to other patterns like
LinalgTilingPattern. The fusion patterns takes options that allows you
to fuse with producers of multiple operands at once.
- The pattern fuses only at the level that is known to be legal, i.e
  if a reduction loop in the consumer is tiled, then fusion should
  happen "before" this loop. Some refactoring of the fusion code is
  needed to fuse only where it is legal.
- Since the fusion on buffers uses the LinalgDependenceGraph that is
  not mutable in place the fusion pattern keeps the original
  operations in the IR, but are tagged with a marker that can be later
  used to find the original operations.

This change also fixes an issue with tiling and
distribution/interchange where if the tile size of a loop were 0 it
wasnt account for in these.

This can be used to distribute large vectors to loops or SPMD.
