In f820625, the -module-dir option was modified to allow it to be joined to the argument value, i.e. `-module-dir<value>` was allowed in addition to `-module-dir <value>`. While this is consistent with its aliasee, '-J', it is not consistent with the way other long options are handled in flang. This also makes it difficult to add another option such as -module-directives since it is not clear if "ectives" is the name of a directory containing .mod files. `-module-dir<value>` is no longer allowed. Only `-module-dir <value>` may be used. `-module-dir=<value>` is not allowed either. However, both `-J<value>` and `-J <value>` are permitted. `-J` was made into the "primary" option and `-module-dir` was made its aliasee instead of the other way around since the former can be both joined and separated while the latter can only be separate.
