Matthias Springer bb273a35a0 [mlir][linalg][bufferize][NFC] Move tensor interface impl to new build target
This makes ComprehensiveBufferize entirely independent of the tensor dialect.

Matthias Springer d1c8df8743 [mlir][linalg][bufferize] Decouple ComprehensiveBufferize from Linalg
The remaining dialects will be decoupled from ComprehensiveBufferize in separate commits.

Matthias Springer 1b2bda8d1a [mlir][linalg][bufferize] Add PostAnalysisStep
This helper struct allows users of ComprehensiveBufferize to inject "post analysis" steps that are implemented after the analysis but before the bufferization.

Matthias Springer 4397a1baef [mlir][linalg][bufferize] Remove remaining linalg dependencies
* Move "linalg.inplaceable" attr name literals to BufferizableOpInterface.
* Use `memref.copy` by default. Override to `linalg.copy` in ComprehensiveBufferizePass.

These are the last remaining code dependencies on Linalg in Comprehensive Bufferize. The next commit will make ComprehensiveBufferize independent of the Linalg dialect.

Matthias Springer a4547dc575 [mlir][linalg][bufferize] Move more helper functions/structs to interface
Move helper functions for traversing reverse use-def chains. These are useful for implementing custom optimizations (e.g., custom InitTensorOp eliminations).

Also move over the AllocationCallbacks struct. This is in preparation for decoupling ComprehensiveBufferize from various dialects.

Matthias Springer 7f153e8ba1 [mlir][linalg][bufferize] Add `isAllocationHoistingBarrier` to op interface
This make `getResultBuffer` in ComprehensiveBufferize independent of the SCF, Affine and Linalg dialects. This commit is in preparating of decoupling op interface implementations from ComprehensiveBufferize.

Matthias Springer 050591478e [mlir][linalg][bufferize][NFC] Move helper functions to op interface

Matthias Springer 95e62eb430 [mlir][linalg][bufferize] Separate pass from ComprehensiveBufferize
This commit separates the bufferization from the bufferization pass in Linalg. This allows other dialects to use ComprehensiveBufferize more easily.

This commit mainly moves files to a new directory and adds a new build target.
