Currently, the sequence of Transform dialect operations only supports a single use of each operand (verified by the `transform.sequence` operation). This was originally motivated by the need to guard against accessing a payload IR operation associated with a transform IR value after this operation has likely been rewritten by a transformation. However, not all Transform dialect operations rewrite payload IR, in particular the "navigation" operation such as `transform.pdl_match` do not. Introduce memory effects to the Transform dialect operations to describe their effect on the payload IR and the mapping between payload IR opreations and transform IR values. Use these effects to replace the single-use rule, allowing repeated reads and disallowing use-after-free, where operations with the "free" effect are considered to "consume" the transform IR value and rewrite the corresponding payload IR operations). As an additional improvement, this enables code motion transformation on the transform IR itself. Reviewed By: Mogball Differential Revision: https://reviews.llvm.org/D124181
