Until now, `-x` wasn't really taken into account in Flang's compiler and frontend drivers. `flang-new` and `flang-new -fc1` only recently gained powers to consume inputs other than Fortran files and that's probably why this hasn't been noticed yet. This patch makes sure that `-x` is supported correctly and consistently with Clang. To this end, verification is added when reading LLVM IR files (i.e. IR modules are verified with `llvm::verifyModule`). This way, LLVM IR parsing errors are correctly reported to Flang users. This also aids testing. With the new functionality, we can verify that `-x ir` breaks compilation for e.g. Fortran files and vice-versa. Tests are updated accordingly.
