[PATCH 5/7] gdb/fortran: Don't include module symbols when searching for types

[Andrew Burgess <andrew dot burgess at embecosm dot com>]

Currently the 'info types' command will return symbols that correspond
to Fortran modules.  This because the symbols are created with domain
MODULE_DOMAIN, but address_class LOC_TYPEDEF, which is the same
address_class as type symbols.

This commit explicitly prevents MODULE_DOMAIN symbols from appearing
when we search for symbols in the TYPES_DOMAIN, this prevents the
module symbols from appearing in the output of 'info types'.

gdb/ChangeLog:

	* symtab.c (search_symbols): Don't include MODULE_DOMAIN symbols
	when searching for types.

gdb/testsuite/ChangeLog:

	* gdb.fortran/info-types.exp: Add module.
	* gdb.fortran/info-types.f90: Update expected results.
