This is a new pattern rewrite frontend designed from the ground up to support MLIR constructs, and to target PDL. This frontend language was proposed in https://llvm.discourse.group/t/rfc-pdll-a-new-declarative-rewrite-frontend-for-mlir/4798 This commit starts sketching out the base structure of the frontend, and is intended to be a minimal starting point for building up the language. It essentially contains support for defining a pattern, variables, and erasing an operation. The features mentioned in the proposal RFC (including IDE support) will be added incrementally in followup commits. I intend to upstream the documentation for the language in a followup when a bit more of the pieces have been landed. Differential Revision: https://reviews.llvm.org/D115093
