* https://discourse.llvm.org/t/rfc-removing-the-quant-dialect/3643/8 * Removes most ops. Leaves casts given final comment (can remove more in a followup). * There are a few uses in Tosa keeping some of the utilities alive. In a followup, I will probably elect to just move simplified versions of them into Tosa itself vs having this quasi-library dependency. Differential Revision: https://reviews.llvm.org/D120204
