[flang-dev] Rewriting f18's history for inclusion in llvm monorepo (checklist)

[Peter Waller via flang-dev]

Hi All,

I've made an issue to track a checklist of what needs to happen to push 
the new history up at https://github.com/flang-compiler/f18/issues/876.

Please comment there or edit the list if you think of further items 
which need addressing.

Regards,

- Peter
