d62b4b08af [mlir][linalg][bufferize] Compose dialect-specific bufferization state 
Use composition instead of inheritance for storing dialect-specific bufferization state. This is in preparation of adding "tensor dialect"-specific bufferization state.

c94b80b438 [mlir][linalg][bufferize][NFC] Allow returning arbitrary memrefs 
If `allowReturnMemref` is set to true, arbitrary memrefs may be returned from FuncOps. Also remove allocation hoisting code, which is only partly implemented at the moment.

The purpose of this commit is to untangle `bufferize` from `aliasInfo`. (Even with this change, they are not fully untangled yet.)

c637e3ea9e [mlir][linalg][bufferize][NFC] Extract func boundary bufferization 
Bufferization of function boundaries is extracted from ComprehensiveBufferize into a separate file. This will become its own build target in the future.
