Fix Bazel and CMake build after LLVM integration

Updated LLVM and TensorFlow SHA and fixed build configuration.

MLIR Linalg now adopts a two-level generation flow: some Linalg op's
op definitions are first generated by a dedicated TableGen backend into `LinalgNamedStructuredOps.td` and then that file is TableGen'ed into
C++ code. The include path needs to be updated to let TableGen find the
generated intermediate TD files.

Closes https://github.com/google/iree/pull/1672
