PR fortran/95091 - Buffer overflows with submodules and long symbols

With submodules, name mangling results in long internal symbols.  This
requires adjustment of the sizes of temporaries to avoid buffer overflows.

* class.c (get_unique_type_string, gfc_hash_value): Enlarge
buffers, and check whether the strings returned by
