Tim Keith 563e65ded1 [flang] Fix .mod file for symbols with same name as generic
When a generic has the same name as a module procedure or derived type,
the latter weren't being written to the `.mod` file. Fix that by calling
`PutSymbol()` on those symbols from the generic. Change `PutSymbol()` to
accept `Symbol *` to make that more convenient.
