[mlir] run the verifier before translating a module

In translation from MLIR to another IR, run the MLIR verifier on the parsed
module to ensure only valid modules are given to the translation. Previously,
we would send any module that could be parsed to the translation, including
semantically invalid modules, leading to surprising errors or lack thereof down
the pipeline.
