Collect equivalent BBArgs right after the equivalence analysis of the FuncOp and before bufferizing. This is in preparation of decoupling bufferization from aliasInfo.
Also gather equivalence info for CallOps, which was missing in the
previous commit.

Instead of checking buffer equivalence during bufferization, gather buffer equivalence information right after the analysis. This is in preparation of decoupling bufferization from BufferizationAliasInfo.
This change also fixes equivalence analysis for scf.if op results, which was not fully implemented. scf.if op results are equivalent to their corresponding yield values if both yield values are equivalent.

Also set insertion point right before calling `bufferize`. No need to put an InsertionGuard anymore.

Also store a reference to BufferizationOptions in BufferizationState. This is in preparation of adding support for partial bufferization.

However, since CallOps have no aliasing OpResults, their OpOperands always bufferize out-of-place.
This change removes `bufferizesToMemoryWrite` from `CallOpInterface`. This method was called, but its return value did not matter.

Use composition instead of inheritance for storing dialect-specific bufferization state. This is in preparation of adding "tensor dialect"-specific bufferization state.

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.)

Bufferization of function boundaries is extracted from ComprehensiveBufferize into a separate file. This will become its own build target in the future.
