The revision adds the handleArgument and handleResult handlers that allow users of the inlining interface to implement argument and result conversions that take argument and result attributes into account. The motivating use cases for this revision are taken from the LLVM dialect inliner, which has to copy arguments that are marked as byval and that also has to consider zeroext / signext when converting integers. All type conversions are currently handled by the materializeCallConversion hook. It runs before isLegalToInline and supports only the introduction of a single cast operation since it may have to rollback. The new handlers run shortly before and after inlining and cannot fail. As a result, they can introduce more complex ir such as copying a struct argument. At the moment, the new hooks cannot be used to perform type conversions since all type conversions have to be done using the materializeCallConversion. A follow up revision will either relax this constraint or drop materializeCallConversion in favor of the new and more flexible handlers. The revision also extends the CallableOpInterface to provide access to the argument and result attributes if available.
