Tim Keith 3d43ea663b [flang] Module file improvements 
Verify that checksums are correct when reading a module file.

Don't write a module file if its current contents are correct.

Don't make .mod files read-only. It doesn't do much to prevent
users from editing them, checksum verification will detect when
it happens, and having them read-only causes problems if you then
compile with another compiler (e.g. PGI).

Tim Keith 96b187efdf [flang] Add support for submodules 
Symbols for submodules have `ModuleDetails` with `isSubmodule` set.
Scopes for submodules have `Module` kind and have a parent scope that
is also `Module` kind.

Scopes for modules now contain a mapping of submodule name to scope
so that we can find them without having to search the scope tree or
re-read their `.mod` file.

The module file for submodule `s` with ancestor module `m` is named `m-s.mod`.
The tree structure of scopes means module file writing is now recursive.
Similarly, reading the module file for a submodule may require reading
the module files of its parent and ancestor. `ResolveNames` now requires
the parent scope to be passed in -- it is not always the global scope.

`test_modfiles.sh` now handles an argument that is a filename glob so
that the test can involve multiple files. This allows `modfile09` to
test reading of `.mod` files for modules and submodules.
