Alex Zinenko b5756fdaa1 Factor out translation registry. ... The mlir-translate tool is expected to discover individual translations at link time. These translations must register themselves and may need the utilities that are currently defined in mlir-translate.cpp for their entry point functions. Since mlir-translate is linking against individual translations, the translations cannot link against mlir-translate themselves. Extract out the utilities into a separate "Translation" library to avoid the potential dependency cycle. Individual translations link to that library to access TranslateRegistration. The mlir-translate tool links to individual translations and to the "Translation" library because it needs the utilities as well. The main header of the new library is located in include/mlir/Translation.h to make it easily accessible by translators. The rationale for putting it to include/mlir rather than to one of its subdirectories is that its purpose is similar to that of include/mlir/Pass.h so it makes sense to put them at the same level.
