[flang] Add missing dependencies for flang/lib/Optimizer/Dialect

[PeteSteinfeld]

Summary

Patch D145640 wasn't building for me because .cpp files in
flang/lib/Optimizer/Dialect depend on the files generated in
.../build/include/llfm/IR. But the .cpp file compilations were being
done before the needed include files were generated.

This patch fixes that by adding dependencies on "intrinsics_gen" to the
CMake files in two directories.

What is intrinsics_gen?

I don't really know, other than it's the thing that builds the files in .../build/include/llvm/IR.

That's the directory that contains the files that were missing when the .cpp compilations were failing.

All builds and tests correctly and looks good.
