Tool for translating from/to MLIR.

mlir-translate is a tool to translate from/to MLIR. The translations are registered at link time and intended for use in tests. An identity transformation (mlir-to-mlir) is registered by default as example and used in the parser test where simply parsing & printing required.

The TranslateFunctions take filenames (instead of MemoryBuffer) to allow translations special write behavior (e.g., writing to uncommon filesystems).
