This relatively small change will allow Flang's frontend driver, `flang-new -fc1`, to consume and parse MLIR files. Semantically (i.e. from user's perspective) this is identical to reading LLVM IR files. Two file extensions are associated with MLIR files: .fir and .mlir. Note that reading MLIR files makes only sense when running one of the code-generation actions, i.e. when using one of the following action flags: -S, -emit-obj, -emit-llvm, -emit-llvm-bc. The majority of tests that required `tco` to run are updated to also run with `flang-new -fc1`. A few tests are updated to use `fir-opt` instead of `tco` (that's the preferred choice when testing a particular MLIR pass). basic-program.fir is not updated as that test is intended to verify the behaviour of `tco` specifically.
