[PATCH] D108687: [flang] Add runtime interface for COMMAND_ARGUMENT_COUNT

[Diana Picus via Phabricator via llvm-commits]

rovka updated this revision to Diff 369054.

Addressed review comments.

In the end I created a new file, command.h, because main.h is in the c-or-cpp style and I'm not sure it's a good idea to touch it. I don't mind hearing otherwise though :)
