[PATCH] D99292: [flang][driver] Add support for `-cpp/-nocpp`

[Andrzej Warzynski via Phabricator via cfe-commits]

awarzynski added a comment.

Make sure that `-cpp\-nocpp` controls command line macro definitions too

As @tskeith pointed out, `-cpp\-nocpp` should also affect command line macro
definitions (on top of standard macro predefinitions). With this change, the
file extension becomes significant in all tests that depend on macros. I've
renamed some of them accordingly. Few other tests are updated to
demonstrate that the new flags work as expected.
