Fortran: make some match* functions static

gfc_match_small_int_expr was unused, delete it.
gfc_match_gcc_unroll should use gfc_match_small_literal_int and then
gfc_match_small_int can be deleted since it will be unused.

gcc/fortran/ChangeLog:

	* decl.c (gfc_match_old_kind_spec, set_com_block_bind_c,
	set_verify_bind_c_sym, set_verify_bind_c_com_block,
	get_bind_c_idents, gfc_match_suffix, gfc_get_type_attr_spec,
	check_extended_derived_type): Make static.
	(gfc_match_gcc_unroll): Add comment.
	* match.c (gfc_match_small_int_expr): Delete definition.
	* match.h (gfc_match_small_int_expr): Delete declaration.
	(gfc_match_name_C, gfc_match_old_kind_spec, set_com_block_bind_c,
	set_verify_bind_c_sym, set_verify_bind_c_com_block,
	get_bind_c_idents, gfc_match_suffix,
	gfc_get_type_attr_spec): Delete declaration.
