[module.unit]p1 specifies that module and import are invalid components of a module name, that module names cannot contain reserved identifiers, and that std followed by zero or more digits is reserved. The first issue (module and import pseudo-keywords) requires a diagnostic, the second issue (use of reserved identifiers) does not require a diagnostic. We diagnose both the same -- the code is ill- formed unless the module declaration is in a system "header". This allows STL implementations to use the reserved module names while preventing users from stealing them out from under us. Differential Revision: https://reviews.llvm.org/D136953
