Ramkumar Ramachandra	0de16fafa5	mlir/DialectConversion: use std::optional (NFC) ... This is part of an effort to migrate from llvm::Optional to std::optional. This patch touches DialectConversion, and modifies existing conversions and tests appropriately.

River Riddle	8c66344ee9	[mlir:PDL] Add support for DialectConversion with pattern configurations ... 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	2022-11-08 01:57:57 -08:00
