[mlir][Linalg] Add canonicalization to remove no-op linalg operations.

linalg.generic/indexed_generic operations on tensors whose body is
just yielding the (non-induction variable) arguments of the operation
can be canonicalized by replacing uses of the result with the
corresponding arguments.

[SLP] remove unnecessary state in matching reductions

This is NFC-intended. I'm still trying to figure out
how the loop where this is used works. It does not
seem like we require this data at all, but it's
hard to confirm given the complicated predicates.
