Up until now PDL(L) has not supported dialect conversion because we had no way of remapping values or integrating with type conversions. This commit rectifies that by adding a new "pattern configuration" concept to PDL. This essentially allows for attaching external configurations to patterns, which can hook into pattern events (for now just the scope of a rewrite, but we could also pass configs to native rewrites as well). This allows for injecting the type converter into the conversion pattern rewriter. Differential Revision: https://reviews.llvm.org/D133142
