After merging https://reviews.llvm.org/D105811, flang-new-driver is no
longer required.

LGTM. One comment/question inline.

Nit: Is there a hyphen at the beginning of the line? Is it required?

Copy & paste error. Thanks for pointing this out, I'll fix it before merging.

flang/test/Driver/code-gen.f90

 ! Although code-generation is not yet available, we do have frontend actions
 ! that correspond to `-c` and `-emit-obj`. For now these actions are just a
 ! placeholder and running them leads to a driver error. This test makes sure
 ! that these actions are indeed run (rather than `-c` or `-emit-obj` being
 ! rejected earlier).
 ! TODO: Replace this file with a proper test once code-generation is available.
