fortran: enable ptype/whatis for user defined types.

	(gdb) ptype type
	old> No symbol "type" in current context.
	new> type = Type type
	     integer(kind=4) :: t_i
	     End Type type

	* f-exp.y (yylex): Add domain array to enable lookup
	in multiple domains. Loop over lookup domains and try
	to find requested symbol. Add STRUCT_DOMAIN to lookup
	domains to be able to query for user defined types.

	* gdb.fortran/type.f90: New file.
	* gdb.fortran/whatis_type.f90: New file.
