After removing host operations from the device MLIR module, it is no longer necessary to provide special codegen logic to prevent these operations from causing compiler crashes or miscompilations. This patch removes these now unnecessary code paths to simplify codegen logic. Some MLIR tests are now replaced with Flang tests, since the responsibility of dealing with host operations has been moved earlier in the compilation flow. MLIR tests holding target device modules are updated to no longer include now unsupported host operations.
